Types Of Stainless Steel For Sheet Metal Fabrication

The 300 series alloys: It is also referred to as austenitic stainless steel and are easy to weld, easy to form and are very ductile.

They have more chromium and nickel contents hence an increased resistance to corrosion when compared to standard steel.

They are normally preferred for the food industries because they are very easy to maintain and clean.

The 300 Series Alloy

The 300 Series Alloy

Stainless Steel 301: It is cheaper compared to 304 stainless steel and can be used as an alternative. It is made up of less chromium and nickel content with more carbon content to resist corrosion when compared to other grades.

It can be used to build parts for applications such as appliance enclosures and trains.

Stainless Steel 304: This grade contains a structure similar to that of austenitic crystal and is popularly used by a wide range of industries globally.

304 stainless steel is often amalgamated with 18 to 8 stainless steels with slight changes in elements.

It can resist corrosion to a certain level and it is easy to handle and can be used in applications.

That is like in food industries to make end products such as tanks  and structural bracketing.

Stainless steel grade 304 is versatile, and has a high tensile strength (621 MPa).

Stainless steel grade 304 has an operating temperature of about 870˚C and is resistant to chemical.

Stainless Steel 304

Stainless Steel 304

Stainless Steel 316: It is an austenitic grade of stainless steel which has molybdenum making more resistant to corrosion.

It is very easy to weld and form and maybe used in making parts that are prone to corrosion such as marine equipment or chemical tanks.

Grade 316 stainless steel is popular because it has a high tensile strength (579 MPa) and an operating temperature of about 800˚C.

It is resistant to chlorides like salt, hence can be used with applications that are exposed to chlorides like salt.

Grade 330 Stainless Steel: This is highly resistant to high temperatures and can be used in applications that require the use of high temperatures and high oxidation levels.

It is also resistant to corrosion and cracking hence can be used in environments that other grades cannot fit in.

Grade 430 Stainless Steel: It has a low tensile strength (450 MPa) compared to grades 304 and 316. It offers resistance to nitric acid and can be used with several applications.

Grade 434 Stainless Steel: Grade 434 stainless steel comes with a tensile strength of about 540 MPa and it has an operating temperature of about 815˚C.

It is therefore stronger compared to grade 430 and offer better resistance to temperature compared to grade 316.

It offers better resistance to pitting than grade 430.

Grade 434 Stainless Steel

Grade 434 Stainless Steel

Grade 420 Stainless Steel: Grade 420 stainless steel is not resistant to chemicals but it has high tensile strength and can resist water, mild acids, food compounds and some alkalis.

It is usually used to make cutlery.

200 stainless steel series: it is best when in combination with 300 series which produces approximately 75% stainless steel.

It comprises of chromium, carbon, manganese and nickel and cold working can be used to harden it but still it cannot resist corrosion.

Ferritic: gives superior engineering properties, more resistant to corrosion, and contains low amounts of nickel and chromium and some contain lead hence cheaper.

Ferritic Stainless Steel Sheet Metal

Ferritic Stainless Steel Sheet Metal

Martensitic: it is made up of molybdenum, chromium, carbon and nickel. It is less corrosion resistant when compared to ferritic.

Duplex: a combination of ratio 1:1 of austenitic and ferritic stainless steels with less allow content and less nickel and more chromium giving it the ability to resist corrosion, pitting and cracking.

It is also pocket friendly and is preferred by many manufacturers.

Precipitation-hardening martensitic: this offers better resistance to corrosion compared to the other steel metals from the same class and can be used for applications that need stronger stainless-steel options.

Fabrication Process To Custom Stainless Steel Sheet Metal Parts

Fabrication process consists of several steps of cutting and forming and joining procedures that are meant to remove or deform stainless steel sheet metal material into the designed shape.

Cutting Stainless Steel

There exist two varying types of stainless-steel cutting processes; shear and non-shear.

Shear cutting: This is popularly used in making parts that are not used in industries.

Shearing, cutting and blanking are some of the processes included in this stage.

The process of cutting, uses a single blade to cut into the material.

Shearing is, basically, the same action as using scissors to cut through a material.

Lower and upper blade cut in a straight line while one blade cuts through, the other one remains constant.

Shear Cutting Of Stainless Steel

Shear Cutting Of Stainless Steel

Blanking is the process of punching holes into the stainless-steel sheet metal.

Non-shear cutting: It is the process especially employed in cutting integral components or parts that require high accuracy and precision by industries that create parts and components in large scale.

Non-shear cutting can be achieved through several methods and some are described below:

-Laser Beam Cutting which uses highly powered laser beams,

-Plasma Cutting which uses accelerated plasma beams to cut sheet metals which can conduct electricity,

-Waterjet Cutting which uses waterjet machines and does not produce heat.

WaterJet Cutting Of Stainless Steel

Forming Stainless Steel Metal

Forming is the stainless-steel sheet metal fabrication process which deforms or bends the metal into the required shape.

Unlike in cutting, where material is subtracted, in forming the material is reshaped and no mass is lost.

The processes in this procedure include stamping, roll forming, bending and stretching.

Bending can be achieved through the use of press brakes or through handwork and the shapes could be u-bends or v-bends.

A Bent Stainless Steel

 A Bent Stainless Steel Sheet Metal

Stretching, involves the use of a stretcher, or hammer and dolly or English wheel to elongate the stainless steel by pulling it without separating it.

Roll forming which is also the same as bending is the process which allows formation of coil shapes by passing it via a pair of rolls.

Joining The Stainless Steel Sheets

This is the last stage in the process of the stainless steel sheet metal fabrication.

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

The assembling can be done through processes such as; brazing, welding, adhesives and riveting.

Welding is the process that joins sheets of metals by adding a filler, blazing is the process that joins two metals through a melted filler, adhesives use bonding.

That is to join stainless steel sheet metal together or by combining other assembling methods together to form a bond between two metal sheets.

Welding Of Stainless Steel Sheet metal

Welding of Stainless-Steel Sheet


After the stainless-steel sheet metal fabrication process.

There are secondary processes done on the created parts and component in order to achieve the finishing and the end product that was designed.

The finishing techniques and procedures available for finishes may include; deburring, sandblasting, coating or annealing.

These secondary procedures are aimed to add more quality to the surface.

Or to improve the applicability and material properties of certain parts such as resistance to corrosion and improved conductivity.

In conclusion, stainless steel sheet metal fabrication is the manufacturing procedure that converts metals into desired shapes, designs and contours.

That is by cutting, bending and assembling.

The process is very flexible and is key in building the tools and equipment which drive the world’s economy.

Surface Treatments For Stainless Steel Sheet Metal Parts

Standard: The standard finish means the part maintains the original state achieved after forming and bending stage.

A welded part may need passivation or pickling to ensure that all of its surface properties are uniform in all the surfaces.

It is the most commonly used surface finish for stainless steel sheet metal.

Stainless Steel Before And After Passivation

Stainless Steel Before And After Passivation

Powder Coating: This method creates a strong and perfect surface finish.

There are alloys of stainless steel like grade 304 and 301 that do not offer much resistance to chemicals.

Such can be countered by the use of powder coating to improve corrosion resistance properties.

Bead Blasting: This process is intended to create a uniform and smooth matte finish by blasting the surface lightly mostly for cosmetic purposes.
