Advantages Of Carbon Steel Sheet Metal

Durable – Carbon steel metal is very strong and can resist shock and is popular in the construction industry.

Carbon steel metal is also resistant to corrosion and rotting and can last for a very long time.

Safe -carbo steel metal is safe because it can resist fire, earthquakes, tornadoes and hurricanes hence preferred for building homes that are safe.

Green -Carbon steel metal is very friendly to the environment since it can be recycled easily.

Economical -Applications like in piping industries, the use of carbon steel metal is preferred because it requires little material to form the thin pipes making it very pocket friendly.

Healthy – Pans and pots made from carbon steel metal offers healthy cooking because they do not react with any type of food unlike aluminum which reacts with some types of food.

Carbon steel metal material heats up quickly and it also lasts longer.

Types Of Carbon Steel Used For Sheet Metal Fabrication

Low Carbon Steel

The carbon content in low-carbon steel metal is at around 0.05 to 0.320%.

It is pocket friendly and very ductile and malleable, that is why it is the one that is preferred by many people and industries.

low carbon steel

low carbon steel

They are normally fabricated through cold work because they are not responsive to heat treatment.

Low-alloy steels of high strength also fall in the class of low-carbon steels but they contain added elements like nickel, copper, molybdenum and vanadium.

All these combined together make up to approximately 10wt% content of the steel.

High-strength, low-alloy steels, are stronger compared to ordinary low-carbon steels because they allow for heat treatment and maintains ductility hence can be formed and machined.

HSLA can better resist corrosion compared to ordinary low-carbon steels.

Medium-Carbon Steel Metal

Medium carbon steel metal has about 0.30 to 0.59% carbon content and the manganese content in it is approximately 0.60 to 1.65%

The properties can be improved by treating it with heat to give it the martensitic microstructure.

It has good resistance to wear and it strikes a balance between strength and ductility.

Medium carbon steel metal

medium carbon steel sheet metal

Only very thin sections allow for heat treatment, although other alloying elements like nickel, molybdenum and chromium can also be used its heat treatment abilities.

Medium-carbon steel metals that are hardened, have more strength compared to low carbon steels.

High Carbon Steel

The carbon content in high carbon steel is approximately 0.6 to 0.99% and contains about 0.30 to 0.90% of manganese.

It is stronger and tougher than the low and medium carbon steel metals, however, its ductility is very low.

This type of carbon steel can resist wear because they are hardened and also tempered.

The two types of high carbon steel metals are die steel metals and tool steel metals and they are made up of additional elements such as tungsten, chromium, molybdenum and vanadium.

high carbon steel

high carbon steel sheet metal

These additional elements improve the hardness and wear resistance properties of the high carbon steel metals due to the fact that it forms carbide compounds like tungsten carbide.

Ultra-High Carbon Steel Metal

Has approximately 1.0 to 2.0% carbon content and is the strongest and hardest compared to the other types of carbon steel.

Carbon Steel Sheet Metal Parts Fabrication Process

Carbon steel sheet metal parts fabrication process consists of several steps including cutting, forming and joining techniques.

They are done either to deform or remove carbon steel sheet metal material forming the required shape.

Cutting Carbon Steel Sheet Metal

There are several methods that can be used to cut into carbon steel sheet metal.

Below is a brief discussion of the different techniques used to cut into the carbon steel metal and it is divided into two classes: shear and non-shear cutting.

utting carbon steel sheet metal

You can learn more about sheet metal laser cutting.

  1. Non-shear cutting

Various processes like the use of vaporization, extreme heat and high pressure to blast abrasives, can lead to cutting through carbon steel sheet metal without having to use shear forces.

There are three main types of non-shear cutting procedures:

Laser cutting: This process uses a high-powered laser beam to melt and vaporize a piece that combines the two sheets together by focusing the laser beam on it.

Emission takes place at wavelength of approximately 10.6mm.

The process is very efficient and cost-effective and are popular in manufacturing industries.

Water jet cutting: Water jet cutting involves using a high pressure with higher velocity stream of water.

Which also contains abrasives for cutting into the carbon steel sheet metal. This involves a high speed of erosion that will lead to very perfect surface finishes.

This is due to the fact that water is used to quench it throughout the entire process and this prevents distortion by heat.

The material must be supported properly to avoid bending caused by the high pressure.

Plasma cutting: Plasma cutting process is almost similar to laser cutting.

plasma cutting

However, it works with thicker carbon steel materials that do not need perfect surface finishes.

It can only work with materials that can conduct electricity which can create beams that are electrically charged with ionized gas called plasma.

The compressed ionized gas is shot through into the carbon steel metal and back forming a circuit converting the carbon steel into a molten form.

And, the scrap is blown away by the already compressed gas.

It produces a rough cutting with an oxidized zone and large burr near the cut.

  1. Shear cutting

This is the process in which the carbon steel material is cut through the application of a shearing force.

It uses a die to hold and support the carbon steel metal sheet material and there is a punch pressing down at the opening of the die to allow for cutting of the material.

Punching: It is where the carbon steel material that has been punched through becomes scrap while the carbon steel material remaining on the die is the desired part.

Blanking: Blanking is the process that involves placing a blanking force to a carbon steel material supported by a die to cut through.

And the material supported by the die is the scrap while the material that was punched is the required part.

Deformation Of Carbon Steel Sheet Metal

Forming give the material the desired shape as well as stiffness and strength and below are some of the procedures done at this stage.

Bending: A process in which a die with specific geometry is used to create bends on the material through punching it.

Some bends are easy to form while others are hard and complex this depends on the desired shape and design.

The shapes in this stage could be U-shape, V-shape and channel shape.

V-shape steel sheet

Hemming: This can be used when shearing techniques are not available, however, it requires a straightedge with no burrs.

This process creates a bend which is round making the interior of the material look like the exterior.

Curling: It is useful when there is need for rounded edges, the rough surface is enclosed within the curl.

It is also recommended for hinging applications.

Rolling: it is a one step process in which a thicker carbon steel metal piece is taken through two or more pneumatically built rollers.

This compress the material into something thinner.

The carbon steel material gets rolled into different shapes when it is rolled through more rollers with varying geometry.

Roll forming: Roll forming is useful when long portions with multiple dimensions are needed.

Roll forming process takes piece of sheet metal with elongated length and takes it through a number of dies that bend step by step forming a more tangled shape.

This process creates various types of tubing like square and cylindrical

Metal spinning: Metal spinning is made up of a cylinder of carbon steel sheet metal.

It is put onto a mandrel where a roller tool creates the shape according to the shape of the mandrel.

Deep drawing: Deep drawing machinery is almost the same as shear punch.

Deep drawing machinery

Only that there is definite difference between die and punch which means the final wall will be the same as the drawn one.

The radius of the punch will be blunt to prevent marrying.

Assembling of the Carbon Steel Sheet Metal Parts.

After the cutting and the bending processes, two or more components may need to be fused together.

This is to form the required product and the assembling can be done through processes such as; welding, fasteners and soldering.

Fasteners: These are hardware machines which automatically form joints between objects. The joints formed through fasteners are not permanent like the ones achieved through welding.

Fasteners are grouped into various categories including inserts, studs, pins, nuts, hooks, cable tie mounts, standoffs, weld nuts, sheet to sheet attachments and captive panel screws.

Each category serves its own purpose different from the rest and for each category there are several hardware choices to pick from.

Soldering: soldering is different from welding since it uses a base metal to join the two parts.


It involves the use of filler metal which is melted through heating and is used in joining the two parts together.

One of the common applications of Soldering is in copper tubes where there is no need to give interest to the strength of the filler material.

Joints created through soldering are very ductile and not very strong and mostly their melting is below 450°C.

Welding: Welding is the process of joining or fusing two parts together through the use of high temperatures.

It is the most commonly used technique in fastening or fusing carbon steel sheet metal parts together.

There are several welding techniques that are available and a choice of any them depends on the type of bond to be created between the two metal sheets.

TIG welding and MIG welding are mostly recommended if the end product must not heat zones that will eventually affect its normal functioning.

How to Control Quality Of Carbon Steel Sheet Metal Parts

Below are some of the ways through which quality is controlled for carbon steel sheet metal parts.

Metallurgical: Metallurgical testing is useful in determining the quality of carbon steel sheet metal parts.

Through analysis of the microstructure of a given carbon steel sample viewed under a microscope.

Hardness: The hardness value test is used to compare different materials and various treatments. Are don through impressing a sample placed on stable platform below a static load.

Hardenability: Hardenability test is used to determine the distribution of hardness as caused by quenching.

Tension: This test shows how a material will respond when under tension applied to it through force.

Ductility: The ductility test shows how much a material can get deformed before it reaches its breaking point.

Fatigue: Fatigue test helps to determine how carbon steel materials respond to reparations of changing loads.

Impact: It is used to determine the energy levels a carbon steel material can absorb when hit by heavy loads.

Wear: Wear resistance test is used to determine the reaction of the steel material to reality conditions.

Corrosion: Corrosion tests are used to determine how a material reacts to chemicals, metallurgical interaction and electrochemical.

Creep: Creep tests help to determine the continued change when deforming the carbon steel material under high temperature.

Creep tests

Magnetic Particle: this test helps to identify discontinuities beneath the surface of the carbon steel material that cannot be spotted through naked eye.

Eddy: Eddy inspection helps to detect defects non-uniformity in the carbon steel material.

Surface Finish Methods You Can Apply On Carbon Steel Sheet Metal

Bead blasting: Glass beads are spread uniformly at the surface of the part through shooting and this forms a satin or matte finish.

This finish is normally used for creating vision and make such surfaces ready for better coatings, this method can be done together with anodizing.

Powder coating: Used to add a protective polymer, which should be a very thin layer, on the surface of the fabricated product.

Powder coating

This procedure creates an attractive finish and is meant to add more resistance properties to the finished part.

Anodizing: Is an electrochemical procedure that puts a sturdy oxide coat on the part and it gives the surface a matte finish but is very brittle.

Chromate conversion coating: Also referred to as chemical film or Alodine, in this process parts are dipped into chemical baths to create a coating and it is recommended for functional components.

Brushing: Is created through polishing the carbon steel with a grit to obtain a satin finish to remove marks from machines and mostly applied on aesthetic applications.
