It is the material that between normal carbon steel and stainless steel and with low alloy content. So corten steel is the carbon steel that added with copper (low Cu), Chrome (low Cr) elements, these elements exist to bring anti-corrosion performances. Besides, it has other advantages like high strength, plastic ductility, easy to profile, welding and cutting, corrosion, high-temperature resistant, fatigue resistant;

Impressive part is corten steel anti-corrosion resistant is better 2 to 8 times of common carbon steel, paintability is 1.5 to 10 times. By these benefits, the steel parts which makes from weathering steel has good performances against from rust, longer durability and less cost. So the material has been mostly saved.

Why to use weathering steel

This steel has been integrated with the new metallurgy methods, advanced technology and processes. Weathering steel (corten steel) is an super steel material and up to top at international level. Impressively anti-corrosive resistance makes weathering steel become a most popular material in out doors decorations and buildings.

When it comes to engaging yourself in architectural or landscaping projects, you might be able to find tons of building materials at your disposal. While each of them definitely tend to come with their fair share of pros and cons, you would want something which would be able to stand the test of time. After all, if that building material would not be durable, there would be no point in spending so much money in to building something.

Nice appearances

That being said, you might not have heard about corten steel, but you would definitely have come across it. With its rusty orange coloring and weathered look, this is something which you might have come across since this is so easy to spot. Other than that, you would also find it to be quite a popular building material for notable sculptures, along with common applications such as roadside piling.

Corten Steel (Weathering steel) Applications

Weathering steel mainly used in railway building, Auto-mobile, Bridge buildings, tower building, Photovoltaic power station and high way buildings, where need to material that exposed in the atmospheric. It also used in container making, oil and gas, sea port construction and drilling rigs, and the vessel parts that containing H2S.

What is weathering steel

As we say, Weathering steel is also called corten steel. Simply put, you would find this kind of a steel to be a trademark of the United States Steel Corporation. The thing with building materials is that you would often find a layer of rust to form over it during the course of time. No matter how much you would try to prevent it, it would definitely creep in. That is why United States Steel Corporation has come up with this idea. By giving a striking material, they would be able to prevent that layer of dust from being formed. Not only that, but it would also eliminate the steel from deteriorating more. As a result, you would not have to worry about getting it painted from time to time.

So, while all this might sound too good to be true, you would also have to look at things from a realistic point of view. This is because while the rust would continue to grow thicker, the steel would become thicker with no intention of becoming stabilized. After it would reach its breaking point, the steel would become perforated and would then need to be replaced. That is why it would be important to keep the difference in environmental conditions in mind when you would be choosing this steel.

How does corten weathering steel work?

With air and moisture being present, all or majority of low alloy steels would have a tendency to rust. The rate at which that would happen would depend on its access to moisture, oxygen, and atmospheric contaminants that would hit the surface. As the process would progress, the rust layer would form a barrier that would prevent the contaminants, moisture, and oxygen from flowing through. This would also then help to delay the rusting process to some extent. After some time, this rusted layer would also separate itself from the metal. As you would be able to understand, this would be a cycle that would repeat itself over and over again.

However, in the case of weathering steel, things would work in a slightly different way. While the rusting process would definitely start off in the same way, the progression would be slightly different. This is because the alloying elements in the steel would produce a rust layer that would be stable and adhere to the base metal. This would then help to form a protective barrier that would prevent further access of moisture, oxygen, and pollutants. As such, you would be able to experience a corrosion rate at a much lower level than what you would normally find on ordinary structural steel.

The metallurgy of weathering steel (corten steel)

The basic difference that you would be able to find between ordinary structural steel and weathering steel would be the inclusion of copper, chromium, and nickel alloying elements. This would help to give the corten steel its enhanced resistance to corrosion. On the other hand, when ordinary structural steel and materials standards for weathering steel would be compared, it has been found that all the other elements seem to be more or less similar.

ASTM A 242

Also known as the original A 242 alloy, this would have a yield strength of 50 ksi (340 Mpa) and the ultimate tensile strength would be of 70 ksi (480 Mpa) for light-medium rolled shapes. As for the plates, that would be up to 0.75 inches thick. In addition, it would have ultimate strength of 67 ksi and yield strength of 46 ksi, with the plates ranging from 0.75-1 inch in terms of thickness.

The rolled plates and sections which would be the most thickly rolled would have ultimate strength of 63 ksi and yield strength of 42 ksi.

As for its categories, you would be able to find it in Types 1 and 2. Just like the name suggests, both of them would be used for different applications, depending upon its thickness. In the case of Type 1, it would most normally be used in the construction industry, housing structures, and freight cars. As for Type 2 steel, also known as Corten B, this would mostly be used in passenger cranes or ships, and urban furnishings.

ASTM A 588

With ultimate tensile strength of 70 ksi and a yield strength of at least 50 ksi, you would be able to find this kind of weathered steel in all rolled shapes. In terms of plate thickness, that would be up to 4 inches thick. As for plates that would be at least 4 to 5 inches, the ultimate tensile strength would be at least 67 ksi. For plates that would range between 5 and 8 inches, the ultimate tensile strength would be at least 63 ksi and yield strength would be at least 42 ksi.

Typical uses of corten steel

As we know corten steel has been widely applied in different industries and projects, so what are the typical famous corten steel projects? Here below we listed some for your references and a further understanding about this steel.

Outdoor usages

As a matter of fact, weathering steel would most popularly be used in outdoor sculptures. Some of the primary examples would include the Barclays Center in Brooklyn, New York, and the Humanities and Arts Complex that is located at Leeds Metropolitan University. Also other famous corten steel sculptures:

Chicago Picasso Sculpture
Barclays Center
The Angle of North
Broadcasting tower in Leeds Beckett University.
and etc.

Bridges, Structurals

Other than that, it could also be used to build bridges and in other large structural applications. Some of these would include the Australian Center for Contemporary Art and the New River George Bridge.

Weathering steel has also been found to be a popular building material for the construction of intermodal containers, marine transportation, along with visible sheet piling. This is something which could easily be seen in London’s M25 motorway which has recently been widened.

When is the first time start to use corten steel

One of the first times corten steel was used was way back in 1971 when it was used to build Highliner electric cars by the St. Louis Car Company. The reason this was done was in an attempt to cut costs compared to using standard steel. However, the sad news is that durability of weathering steel did not seem to hold up as per expectations as rust holes started to appear in the cars. Upon further inspection, it was found that painting contributed to the problem. This is because weathering steel that has been painted would not be as much resistant to corrosion as conventional steel. This means that sufficient amount of time was not given for a protective layer to be formed over the steel. In 2016, these cars seemed to have gone out of the picture for good.

Premium outdoor steel material

Another aspect where you would find corten steel to be quite used is for outdoor construction and landscaping. Since it would be made of alloys that would cause the surface to develop a self-protecting rust, it has been found to be quite a favorite. The insulating patina would resist corrosion which would mean that no weather-proofing or painting would be required. In addition, it would also not compromise the structural strength of the steel.

The reason why weathering steel is preferred by so many of the landscaping designers is because of its versatility. This is because the benefits seem to range ahead more than its warm hue. Generally, you would be able to find it in plate and sheet form. With its durability and strength being combined, along with minimal thickness, it would allow itself to be served in situations where a concrete wall would overwhelm its surroundings or would not fit. Simply put, the versatility of weathering steel seems to know no bounds and would only be limited by the imagination of the designer.

Thanks to its midcentury industrial flavor and no frills, corten steel has been found to fit quite easily in to garden plans of contemporary nature. Since steel seems to have a slim and nice profile, minus the bulkiness of a concrete wall, it would really allow the true nature of the garden to come across. In fact, there would be so many different options that could be explored in this case.

Corten steel advantages

When looking at this specific kind of steel, it would make complete sense to take a look at some of the benefits. Continue reading below for that:

Low maintenance

When using weathering steel that has been exposed, periodic inspection and cleaning would be amongst the only things that would be required as far as maintenance is concerned. In terms of periodic cleaning, that would include rinsing the rusted surfaces with water in order to clean off any contaminates or natural debris. Other than that, dings and scratches would be benefitted by the oxide structure as it would heal through its own natural development without incurring the need for replacement.

Long term performance and cost savings

Since we are talking about long term investment, you would have to take a look at the savings that you would be able to enjoy. This is because if there would be no scope of savings, then there would really be no point in using corten steel for your construction projects.

Therefore, thanks to the durability of corten steel, you would be able to enjoy long term cost savings. This is something which could easily be realized by looking at the buildings which were built almost fifty years ago. In fact, this is being used throughout the world because of its durability and long term cost savings. By utilizing the protective and living nature of this material, it would also help to eliminate the dear costs that would be associated with painting. Not only that, but whole life costs could also be taken away with paint maintenance being done on the site. In cases where access for maintenance of furniture would be difficult or dangerous, or where the disruption of traffic would need to be minimized, then weathering steel would seem like an ideal choice.

Environmental benefits

Just like it would be important to save up on costs, it would be important that you do that while protecting the environment. With exceeding LEEDS requirements, along with other green qualities such as being made from content that has been recycles and 100% recyclable, you would be making a huge contribution to the environment. All you would have to do is browse a bit through the internet and you would be able to find a whole range of information being displayed there.

Dynamic texture and appearance

Weathering steel that has been aged will help to bring forth a multi-dimensional aspect to the appearance of buildings. This is because the patina would be able to transform multiple times a day, from wet to dry and back again. This would also bring along with it a sense of wonder and depth. In short, this steel would become much more than what you had anticipated. You would be able to realize the subtle appearance that would be hiding behind the exposed surfaces, waiting to be discovered and experienced in a new way. As such, you would be able to find very few building materials that would be able to offer this level of complexity and sophistication. With a variegated character and rich tones, the patina would continue to improve and blend with age. With the oxide layer further developing, earthier tones would come to light.

Minimizing lead time and cost

If you would like to get the minimal cost and most streamlined application, then it would be best to use raw corten steel. This is because it would help to reduce both lead times and cost that would be associated with cladding materials. When you would initially be applying this steel, you would be able to notice a flash of rust that would settle itself. However, that would not be something that you would need to be worried about since it would run off and bleed on to the adjoining surfaces. If you would like to handle this, then a catch system or gutter could be included in to the design. This would help to transfer or hide loose ferrites.

Limitations of weathering steel (corten steel)

Just like with any other sort of building material, weathering steel also seems to come with its own share of limitations. But this is not something which should come as a surprise. In fact, it would be good if you would get to know more about it. In this way, you would be able to make a smart and rational choice at the end of the day.

High chlorides content

Environments where the protective rust layer would spontaneously not be able to form on corten steel would be coastal environments. This is because the amount of airborne sea salt particles would be quite high. When the soil would continuously be deposited on to the surface, it would tend to develop the rust product. As such, it would then cause problems to the development of the inner protective oxide layer.

It would be for this reason that you should stay away from using corten steel products that would use high amounts of salt (chloride) as an initiator to the rust layer. This is because over the course of time, they would display the non-adherent nature of the oxide layer. In short, they would not provide the protective layer that they were initially supposed to provide.

De-icing salt

When using weathering steel, it would be highly recommended that you do not use de-icing salts as this would lead to problems in some cases. In usual cases, you would not find this to be an issue unless concentrated and consistent amounts would be deposited on to the surface. This would continue building up if rain would not be present to wash off this buildup.

Pollutants

You should avoid environments where there would be high concentrations of industrial pollutants or corrosive chemicals. While these kinds of situations would rarely be encountered today, it would not hurt to remain on the safe side. This is because several studies have brought to light that industrial environments which would contain low to normal levels of pollutants would help the steel in forming the protective oxide layer.

Retention or drainage traps

Continuous damp or wet conditions would prevent the protective oxides from crystallizing. This would especially be the case when water would be allowed to accumulate in pockets, also known as retention traps. This is because these areas would not be able to dry out completely, thus they would experience brighter colors and higher rates of corrosion. Dense vegetation and damp debris which would be growing around the steel could also add to the surface moisture retention being prolonged. As a result, you should avoid debris retention and moisture. In addition, you should also make it a point to provide sufficient amount of ventilation to the steel members.

Staining or bleeding

The initial flash of surface weathering to corten steel would typically lead to heavy rust staining on all the surfaces nearby, particularly concrete. This could easily be solved by getting rid of designs which would drain the loose rust products on to nearby surfaces.

Thus, that would bring us to the end of the discussion where weathering steel is concerned. Hopefully, all this information would be sufficient to help you make the right decision.

Plasma Cutting Service for Steel – Tips and Guide https://www.octalsteel.com/plasma-cutting-service/ https://www.octalsteel.com/plasma-cutting-service/#respond Tue, 06 Feb 2018 14:58:51 +0000 http://www.octalsteel.com/?p=4125 Plasma cutting technology used a lot in steel and metal cutting processes, especially when integrated with CNC plasma arc cutting. So how much do you know about this cutting technology? And how is the differences between other metal cutting methods.

Below articles we will tell you all the tips and guide if you need this plasma cutting service.

What is Plasma Cutting?

Plasma cutting method is to use the heat that generated from high temperature plasma electric arc to cut the steel parts. During cutting processes, metal material will be melting and evaporated, then to use plasma power to erase the metal melting fusions.

History about Plasma Arc Cutting Tech

Plasma Cutting was developed from plasma welding in the 1960s, and then evolved as an extremely effective method in the 1980s to cut sheet and plate metal. It possessed the benefits over conventional “metal against metal” cutting of generating zero metal clippings, providing precise cuts, and creating a more refined edge compared to oxy-fuel slicing. At the beginning plasma cutters were huge, fairly slow and costly and, for that reason, were inclined to be used for repetitive cutting styles in “mass production”.

Cutting Material Types

As Plasma cutting is a technique that cuts via electrically conductive materials using an accelerated stream of hot plasma. It could cut many types of material including different steels.
Common materials cut using a plasma torch include carbon steel, alloy steel, stainless steel, aluminum, brass and copper, even though various other conductive metals could be cut too.

What it is used for?

Plasma cutting is frequently utilized in auto repair and restoration, manufacturing workshops, salvage and scrapping operations, and industrial construction. Because of the very high speed and meticulous cuts coupled with low price, plasma cutting has a wide range of uses from huge industrial CNC operations all the way down to modest hobbyist shops.

Plasma Cutting Guide and Processes

The simple plasma cutting procedure requires producing an electrical channel of superheated, electrically ionized gas plasma from the plasma cutting tool itself, via the material to be cut, consequently creating a full electric circuit back to the plasma cutter through a grounding clamp.

It is actually done by a pressurized gas (oxygen, air, inert among others subject to material getting cut) which is forced from a concentrated nozzle at very fast speed to the piece getting cut. Inside the gas, an electric arc is created, between an electrode close to or incorporated into the gas nozzle and the actual work piece. A portion of the gas is ionized by the electric arc, resulting in a channel of plasma that is electrically conductive. Simultaneously, most of the high-speed plasma and pressurized gas blast away the scorching molten metal, as a result separating slicing through the material being worked.

Good option to cut both thin and thick steel plates

Cutting with plasma is an efficient method of slicing thin as well as thick steel plates and metal materials. Hand-held torches are able to cut steel plates as thick as 38 mm (1.5 in), and more powerful computer-controlled torches are able to slice steel as much as 150 mm (6 in) thick. Given that plasma cutters can generate an extremely hot and very focused “cone” to do the cutting, they can be invaluable for cutting metal sheets with more shapes and profiles in rounded or angled designs.

How CNC (computer numerical control) integrated in Plasma Cutting

Similar to various other machine equipment, CNC (computer numerical control) technological innovation was used on plasma cutting equipment in the latter part of the 1980s and into the 1990s, providing plasma cutting devices superior versatility to cut various designs “on demand” according to specific details which were programmed into the numerical brain of the machine.

These CNC plasma cutting pieces of equipment was, however, usually confined to cutting designs and components in flat steel sheets, employing just 2 axes of movement (known as X Y cutting)
Starting methods

Plasma cutting tools make use of quite a few techniques to start the arc. In certain devices, the arc is made by connecting the torch with the material being cut. Other cutting tools apply a high voltage, high-frequency electrical connection to create the arc. This technique has quite a few drawbacks, such as the danger of electric shocks, troublesome to fix, maintaining the spark gap, along with the large level of radio frequency emissions.[5] Plasma cutting tools operating close to delicate electronic products, like CNC equipment or computing devices, initiate the pilot arc by other methods. The nozzle and the electrode come into contact. The nozzle is the cathode while the electrode is the anode. Once the plasma gas starts flowing, the nozzle blows forward. A third, but not as popular technique is capacitive discharge into the main circuit through a silicon operated rectifier.

CNC Plasma Cutting Methods

A number of plasma cutter makers construct CNC cutting benches, and some installed the cutter in the cutting table. CNC tables make it possible for a computer to operate the torch head creating clean crisp cuts.

Nowadays CNC plasma cutting services

Today’s CNC plasma equipment are able to cut thick material on multiple axes, making it possible for complicated welding joints which are impossible with other methods. For thinner metals, plasma cutting is slowly being swapped out for laser cutting, because of the laser cut has exceptional hole-cutting capabilities.

(A specific application of CNC Plasma Cutters is in the HVAC field. Software analyses details on ductwork and produces level styles to be cut on the cutting table using a plasma torch. This technological innovation has significantly improved efficiency within the sector since it was introduced at the start of the 1980s.)

CNC Plasma Cutting services also can be used in various workshops to produce beautiful metalwork. For example, commercial and residential home signs, wall art, designs, street address signs, and exterior garden art.

Recently there was even further advancement. Normally, the cutting tables of the machines were horizontal, however, vertical CNC plasma cutting devices are on the market, offering a compact footprint, greater flexibility, most effective safety and quicker functionality.

CNC Plasma Cutting Configurations

CNC Plasma Cutting has 3 primary configurations, which are mostly differentiated by the kinds of materials before working as well as the mobility of the cutting head.

a. 2 Axis Plasma Cutting (2 D)

It is the most popular and traditional kind of CNC Plasma Cutting. Producing level profiles, in which the cut sides have a 90-degree angle to the surface of the material. CNC Plasma Cutting beds, the high powered ones, are set up in this manner, are capable of cutting profiles from metal plate as thick as 150mm all the way up to 30mm thick.

b. 3 Axis Plasma Cutting (3 D)

Just as before, a procedure for creating level profiles from a thin steel plate or sheet metal, but with the advent of an extra rotational axis, the CNC Plasma Cutting machine cutting head is able to tilt even while going through a standard 2-dimensional cutting route. The outcome of this is cut edges at angles besides 90-degrees to the surface of the material, for instances an 30-45 degree angles.

This angle is constant all the way through the material’s thickness. This is usually utilized in conditions where the profile getting cut will be utilized together with a welded fabrication as the edge angle forms a part of the weld groundwork. Once the weld preparation is carried out in the course of the CNC plasma cutting procedure, supplementary functions like milling or machining are often eliminated, thereby minimizing cost. The angular cutting ability of 3D plasma cutting can even be used to produce countersunk holes as well as chamfer edges of profiled holes.

c. Steel Pipe, Tube by Plasma Cutting

This cutting method is applied to the processing of tube, pipe or any kind of extended section, like H beams, C beams, L steel profiles etc. During the cutting processes, the plasma cutting torch will stay fixed at the same time the workpiece is pushed through, and revolving around the longitudinal axis.

Where ever, there are certain settings as with 3D Plasma Cutting, the cutting torch is able to turn and revolve. This enables angled cuts to be produced throughout the thickness of the section or tube, usually exploited in the fabrication of process pipework in which cut pipe could be supplied with a weld preparation instead of a straight edge.

How is Plasma Cutting Tech going to develop

The point is to get the high performance cut. In the previously years, plasma torch makers have designed a new version with a more compact nozzle and a slimmer plasma arc. It makes plasma cut edges could reach laser cut accuracy. There are some manufacturing companies have integrated accurate CNC control with the new nozzle, to get a more precisely cuts that nearly do not require any further processing and finishing.

Costs compared to other cutting methods

The costs for plasma cutting is getting reduced, previously plasma torches were expensive. Because of this they were often only located in specialized welding shops and really well-stocked private shops and garages. But, present-day plasma torches are getting more affordable, and today is within the budget of most hobbyists. Outdated equipment usually has a big weight, even it’s a portable model, while a number of more modern types with inverter features don’t weight that much at all, but are equal to or beyond the capacity of the old styles.

Waterjet Cutting Services – Another Good Option to Cut Steel https://www.octalsteel.com/waterjet-cutting-services/ https://www.octalsteel.com/waterjet-cutting-services/#respond Fri, 02 Feb 2018 15:38:11 +0000 http://www.octalsteel.com/?p=4120 Waterjet cutting is to use high pressure water to cut or profiling steels and especially for highly brittle materials. It delivers smooth and precise cuts through the mechanical sawing action. This is a versatile process in that it cuts through almost every material.

Octal provides customize waterjet cutting services according client requirements.

Things you should know about waterjet cutting and advantages

Here are a few things about the waterjet process worth noting:

• This process delivers precise cuttings, according to a person’s needs and specifications. In short, it can deliver high tolerance parts because of its narrow kerf width.
• It is slow when compared to other metal fabrication methods.
• It is one of the most expensive techniques in the market. This mostly applies when combined with plasma.
• CNC technology integrated in, fast program, fast layouts, CAD in.
• Cold cutting, no hot transformations
• No pollution, no harmful air and dust generated
• The only way to cut compound materials
• Edge smooth, no second cutting required
• One time process of perforation, cutting and profiling
• Lower cutting cost
• High Auto controlled
• 24 hours continuously working
• No need to change cutting torch
• Less cutting blurs.
• No cutting direction limits. Different profile different degree cutting.

2 cutting types by waterjet

Generally, there are two water cutting process, namely the pure water cutting technique and abrasive waterjet cutting process.

Pure water cutting

The pure water cutting technology is meant for soft materials such as food, rubber, textiles and leather. During this technique, water is pressurized into high levels then forced out through a small sapphire or ruby, releasing an intense cutting steam. The steam jet is believed to move 2.5 times the speed of the sound. This is the reason the pure water cutting technology cuts at a high rate, giving out powerful and precise cuttings.

Abrasive waterjet

On the other hand, the abrasive waterjet cutting technology is meant for hard materials that the pure water technology cannot cut through. As the name suggests, the water nozzle is replaced with an abrasive cutting head. The water steam creates a vacuum thus drawing the abrasive into a chamber facilitating the production of powerful abrasive jet steam.

This is the commonly known waterjet cutting steel process. The abrasive process cuts through nay material such as slab, glass, sheetmetal and aluminum, among others.

How does the waterjet cut intensifier pump works?

As we all know, the waterjet process operates on ultra high pressure to cut through materials. This process starts off with an intensifier pump. This pump creates the ultra high pressure needed to perform various tasks. The intensifier pump is fitted with a large horsepower motor.

Additionally, it uses a hydraulic pressure. This is how the hydraulic pressure is created and powers piston in a cylinder. Here is a list of other requirements used in this process:
A low pressure water inlet
Water off valve
Boost pump
Accumulator
Inlet check valves
Water filler
An intensified piston
Abrasive metering system and a cutting head.

Key point in waterjet cutting systems

The key point to make waterjet cutting is the clean water system is connected to the low pressure inlet. The water is then forced into the inlet filter through the inlet check valves until it reaches the hydraulic pump. This is the stage where water is pressurized. During this stage, the water pressurizes the hydraulic fluid in the hydraulic pump. The pressure then forces water out of the intensifier and finally into the accumulator. The water then flows into the high pressure tubing into the cutting head. The water flow is controlled by the off valve. This valve allows people to achieve their desired cuttings while using the waterjet cutting process. The abrasive is mixed with high water pressure in the mixing chamber.

How does the intensifier work in waterjet cutting services?

People are always asking how the intensifier is able to create the ultra high water pressure. The larger hydraulic cylinder pushes the small piston in a cylinder full of water. This is how the ultra high water pressure is created. High water pressure enhances the cutting process.

How is waterjet cutting head working

Let us shift our gears and look at how the waterjet cutting head works. The high pressure water can be delivered into the cutting head in two ways. It can be through the hose or the high pressure tubing. The water is then applied to an orifice to help resist abrasion of high pressure water. It is mostly made of sapphire and diamond. The orifice is entitled the task of creating the water stream. Not all materials can be cut by the water stream. There are cases where a person will be required to add an abrasive to the water stream to cut through hard materials such as stone, plastic, aluminum and steel, among others.

The abrasive is the one that does the actual cutting. It is made up of crushed garnet. Consequently, there are other materials a person can use for special applications. Lastly, machines can be cut to meet a person’s exact needs.

Materials that could be used for waterjet cut

Waterjet cutting services could be applied for different materials, metals as carbon, alloy, aluminum, stainless steels, also the brass, copper. Other materials like carbon fiber, plastics, glass.

Flame Cutting (Oxy Fuel Cutting) – A Method to Cut Steel https://www.octalsteel.com/flame-cutting-oxy-fuel-cutting/ https://www.octalsteel.com/flame-cutting-oxy-fuel-cutting/#respond Fri, 26 Jan 2018 14:02:44 +0000 http://www.octalsteel.com/?p=4106 Flame cutting (also known as oxy fuel cutting), it is to use the heat burned from oxy fuel gas, to cut steel materials or the hard metals to the panels or profiles required. It can cut steel thickness from 1 mm to 1200 mm. And in most cases it used to cut steel plate thickness more than 20 mm, since oxy fuel cutting usually brings big tolerance. For steels under 20 mm, better to use other cutting method like laser cut or waterjet cut. (For to get a high precision.)

On the other hand, as oxy fuel cutting technology is developed nowadays, with a proper oxy fuel gas mixture and good temperature control, also we could get a high precision flame cutting (a quality flame cutting). Especially with CNC flame cutting technology integrated in, it has been widely used in steel parts manufacturing processes.

What is Flame Cutting or Oxy Fuel cutting

Flame cutting (oxy fuel cutting or oxy acetylene cutting), as it’s name, with oxy fuel gas burning through a cutting torch, makes a flame and with the flame heat to cut steels. It is an oldest way in hot steel cutting activities. The cutting torch is designed to provide Oxygen fuel gas for to burn the iron oxide, in this way to guarantee the stable of the temperature and get better cutting performances.

Why flame cut steel used much in cutting steels

Flame cut steel is an old and very common cutting steel technology for cutting steels. As we know, metal fabrication entails cutting, heating and welding steel. There are numerous techniques used to shape steel, flame cut steel is one of these techniques and with hardware development now you are able to get a quality flame cutting steel parts. It entails the use of fuel gas and oxygen to cut shapes from the steel plate. This technique is gaining widespread popularity for various reasons.

Here are some of the reasons and advantages:

Lower cost and lower investment (Flame cutting machine is cheaper than Laser cut or waterjet machine. Even with a oxy fuel cutting revolver you can do the cuts.)
The only way to cut steel with big thickness (to cut thick steel).
It is relatively affordable when compared to other techniques.
It can cut through a large metal surface area. This thickness ranges from 1 millimeter to 1000 millimeters.
This process is portable. It can be used in different locations, apart from a physical workshop.
CNC flame cutting technology integrated

Disadvantages

• Cutting parts in bigger transformations (Because of the heat melting will makes larger cutting material)
• Operators should have highly skills and much experiences (To get a better precision size and avoid more hot transformation)

How does flame cut steel plate (oxy fuel cut) process work?

Ever asked yourself the above question? If yes, you are at the right place. The flame cutting steel plate process is thermo-chemical. This process requires intense heat commonly referred to pure oxygen. This oxygen fuel can be found in bulk systems and cylinders. Non pure oxygen reduces the cutting speed of steel. Consequently, pure oxygen fuel can mix with impurities through leaks, bad hoses and improper connections. Pure oxygen fuel should be carefully used or it risks serious injuries.

Cutting materials types

The flame cutting steel process can be use for numerous purposes, provided the oxide formed has a low melting point when compared to the material being cut. This is the reason the oxy fuel cutting process cannot be used with other materials. A perfect example is aluminum.

Flame Cutting (oxy fuel cutting) Types

Flame cutting types mainly divided in torch cutting and CNC flame cutting (machine flame cutting table).

Flame torch cutting

Flame torch also called fire gun. With different gas, the torch has different structural. Most used is Oxygen-Acetylene gas torch, acetylene pressure at 0.01 to 0.12 Mpa, Oxygen pressure 0.50 to 1.0 Mpa. Two different gas burned in it’s own channel and mixed together in oxy fuel cutting torch, the flame could be adjusted manually. This type of oxygen cutting mainly used to re-cutting to remove the defects from the steel billet cutting or steel straightening.

CNC flame cutting for steels

CNC flame cutting is processed by CNC cutting machine, that is to use CNC technology to drive the flame cutting table and cutting torch, to cut steel plate, steel sheet and other metal materials. CNC flame cutting equipment integrated the machine, table, electricity, and flame torch. So it includes three big part: CNC control systems, flame cutting systems, and drive systems.

CNC flame cut steel advantages is it can cut big thick steel plate, lower cost, but disadvantages also the same with common flame cut. Which is big transformation, lower precision, slow cutting speed takes long time for preheating, perforation slow, and is hard for all the auto operations. So it’s application limited to carbon steel, and thick steel plate cutting. For the thin steel plate cutting under 20 mm, it is almost substitute by laser cut, or plasma cutting technical.

How can the flame cutting performances could be enhanced?

There are two factors which influence the performance of the flame cutting process, namely the nozzle selection and the fuel type. These two factors can increase or reduce both the labor cost and the cutting speed. In addition to this, the oxy fuel jet and the gas used influence the cutting period used to cut through a material. In most cases, oxygen fuel is mixed with other fuel gas such as propane, methane; acetylene, propylene and MAPP to reach achieve the ignition temperature. The flame cutting steel temperature must below the material’s melting point. Afterwards, pure oxy fuel is passed through the preheated area to kick off the flame cutting process.

The chosen ignition gas depends on whether the process is mechanized or manually handled, the material type and the work being handled. A gas is not suitable for use if doesn’t generate the required heat or if it exceeds your set budget.

Flame cutting thickness range for steel plate

This is among the commonly asked questions when people are inquiring about the flame cutting process to cut steel plate or steel panels. As earlier stated, this process can be traced way back when industrialization was at peak. It is proven that this process cuts up to 100 inch material. It is evident this process simplifies material cutting task.

All thin material must be intensely preheated to enhance the cutting speed. Additionally, the preheating process improves the cutting process. This preheating process remains constant for all thick materials.

The point is, The thickness of the steel being cut depends on the amount of oxy fuel being delivered during the cutting process. The fuel gas and pure oxygen can be adjusted to deliver smooth cut surface, depending on a person’s needs.

Cutting temperatures

Generally the preheating process entails heating a material between 1600-1800 degrees F.
Secondly, pure oxygen is passed through the heated area to facilitate burning or oxidization. This is the reason a person can achieve an excellent final cut surface. It can be a sharp slag-free lower edge, sharp top edge or a flat cut surface.

How to get a quality flame cut steel panel with higher precision?

There are numerous factors that control the flame cutting process, so to get a quality flame cut steel panels or parts with higher precision. There are some factors we shall be noted:

• Carefully studying and understanding the working process. It is advisable to hire a professional service provider if you find this process difficult or stressful.

• Selecting a perfect tip for achieving your desired cuts. There are numerous tips people can use to achieve their desired results. Selecting a simple technique makes it easy to achieve your desired outcome.

• Choosing the correct oxy fuel cutting pressure. People have different needs. Choosing the correct oxygen pressure ensures you achieve your desired quality cut.

• Taking the preheating process seriously. Some people take this process lightly. The preheating process determines if the entire flame cutting process will be a success or not.

• Using the right cutting speed to achieve your desired goals within the set time frame.

There is no doubt the it can help people cut various materials into different shapes at a pocket friendly price. We shall note that not everyone attains a high quality or desired precision flame cutting parts, but with above notes at least you will not get a failed cuts.

Laser Cut Metal Services – Steel Profiling/Cutting as Customized https://www.octalsteel.com/laser-cut-metal-steel/ https://www.octalsteel.com/laser-cut-metal-steel/#respond Tue, 23 Jan 2018 13:19:15 +0000 http://www.octalsteel.com/?p=4093 Laser cut metal is a processed metal by laser cutting technology. Metal materials mainly types in sheet metal (steel plate) and fabricated in carbon, alloy or stainless steel.

About laser cutting

Laser cutting is to cut different materials especially steel metals with the help of laser beam. It is majorly used for industrial manufacturing applications, profiling metal connections for different equipment and structural parts. But now a day’s it also has been used for different purposes, such as wall art decoration, urban construction, auto-mobile manufacturing etc.

Why Laser cutting is getting popular in steel and metal cutting processes? Most is because of the reasons below.

Economic
High precision (up to +/- 0.05mm)
Rigorous cutting edge
Highly processing speed
Excellent cut quality
Less contamination
Auto and manually profiling options
CNC technology in
CAD connection
More material types
Small slot
Low transformations

Octal provide metal laser cutting services, which means we can cut steel plate, metal sheet as customized to different panels, screens, wall art etc. And before you are ordering this service, there are several things you need to know about laser cut metal technology.

Laser Cut Metal Material Types

What kind of material could be processed by laser cutting technology?

Yes, mostly laser cutting is used to cut mild steel (carbon and alloy steel) aluminum, stainless steel plates, metal sheets and other substances. We are listing steel material standard and grades for laser cutting so you can to decide what materials you prefer.

Cutting Thickness

Laser cutting method is best suited for cutting mild steel plate which has a thickness up to 1.25 inch (36 mm). After one inch, the cutting process will become difficulty and it need to be perfectly set which requires to configure each thing correctly. Like installing the material, checking the nozzle condition, beam quality, and gas purity. We know how to use laser technology to laser cut metal.

Laser cut metal tolerances

For different thickness of steels, different length and width tolerances standard will be applied, and normally as below:

• Steel thickness under 1.0mm, tolerances is +/- 0.12 mm.
• From 1.0 mm to 3.0 mm, tolerances allowed +/- 0.15 mm.
• From 3.0 mm to 6.0 mm, +/- 0.20 mm.
• 6.0 mm to 15.0 mm, laser cutting tolerances at +/- 0.25 mm.
• Up 15.0 mm to 20.0 mm, laser cut tolerances at +/- 0.75 mm.

Why laser cutting keeps material with precisely sizes

It’s not a fast process, especially on the mild steel, it looks like a burning process in which the extreme heat of the beam is used rather than the preheat flame. In this case, the speed is mainly maintained by keeping a check on the reaction of iron and oxygen. The precision of the laser cut metal is excellent. It creates a very tiny kerf width which helps in cutting even the precise contours as well as the small holes. With laser cutting, the edge quality is outstanding, with perfectly square edges and no or very little trash.
