Forming Stainless Steel Sheet Metal

Sheet metal is metal formed by an industrial process into thin flat pieces.

Forming stainless steel sheet metal.

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. This added hardness increases the amount of force needed to place a bend on a stainless steel sheet. Stainless steels are alloy steels with iron as the primary constituent and chromium nickel and manganese as principal alloying elements. It should also be noted that austenitic stainless steels can t be heat treated meaning that cold forming may be your only option.

These alloys also tend to respond well to cold forming. Extremely thin sheets are considered foil or leaf and pieces thicker than 6 mm 0 25 in are considered. Air bending with a v die. The sheet metal is bent so plastic deformation is reached.

Chromium and nickel give stainless steel its stain resistance and attribute to the hardness of the metal. Use it for high pressure applications in caustic environments. Also known as duplex stainless steel it has twice the strength of 316 stainless steel. 2205 stainless steel resists cracking even when faced with a combination of tensile stress corrosive chemicals and heat.

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. Thicknesses can vary significantly. Item 168753 model 11786. That prevents the metal from regaining its former shape.

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. 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.

An example drawing note might read material. Sheet metal forming bags hold any shape workpiece steady while you pound on it with a hammer. Stainless steel sheet 16 gauge 304 2b the rolling process also introduces a grain direction in the microstructure of the sheet. As you bend a stainless steel sheet the bend area cold hardens increasing the amount of pressure required to finish the bend.
