Forming Stainless Steel Sheet Metal

Forming blocks and punch sets for domed shapes.

Forming stainless steel sheet metal.

They are called stainless because a chromium or nickel oxide film forms on the sheet surface effectively protecting the steel against corrosion. This micrograin runs parallel to the edge of the ribbon of sheet metal as it comes out of the roller. Air bending with a v die. That prevents the metal from regaining its former shape.

Use it for high pressure applications in caustic environments. Also known as duplex stainless steel it has twice the strength of 316 stainless steel. Chromium and nickel give stainless steel its stain resistance and attribute to the hardness of the metal. Bending is a forming process in which sheet metal is bent into the desired shape by applying bending stress.

In addition elon has specified 3mm thick stainless steel which greatly increases forming tonnages required. Sheet metal is metal formed by an industrial process into thin flat pieces. This added hardness increases the amount of force needed to place a bend on a stainless steel sheet. An example drawing note might read material.

These bags are commonly used for initially shaping sheet metal also known as roughing before it s finished on a solid surface such as a forming block dolly or anvil. Thicknesses can vary significantly. Typical automotive skin panels are just 0 65mm thick so 3mm thick is a huge increase in material mass and means the press has to be many times larger to stamp thicker 3mm material successfully. Another good alternative is duplex stainless steel which combines the properties of austenitic and ferritic stainless steels.

The sheet metal is bent so plastic deformation is reached. Stainless steels are alloy steels with iron as the primary constituent and chromium nickel and manganese as principal alloying elements. Hillman 12 in x 24 in cold rolled steel expanded sheet metal. Sheet metal forming bags hold any shape workpiece steady while you pound on it with a hammer.

These alloys also tend to respond well to cold forming. 2205 stainless steel resists cracking even when faced with a combination of tensile stress corrosive chemicals and heat. Tour trusted services provider. It should also be noted that austenitic stainless steels can t be heat treated meaning that cold forming may be your only option.

As you bend a stainless steel sheet the bend area cold hardens increasing the amount of pressure required to finish the bend. Sheet metal is one of the fundamental forms used in metalworking and it can be cut and bent into a variety of shapes countless everyday objects are fabricated from sheet metal.
