Forming Stainless Steel Sheet Metal

The sheet metal is bent so plastic deformation is reached.

Forming stainless steel sheet metal.

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. Chromium and nickel give stainless steel its stain resistance and attribute to the hardness of the metal. Item 168753 model 11786. These alloys also tend to respond well to cold forming.

Another good alternative is duplex stainless steel which combines the properties of austenitic and ferritic stainless steels. Use it for high pressure applications in caustic environments. Hillman 12 in x 24 in cold rolled steel expanded sheet metal. Also known as duplex stainless steel it has twice the strength of 316 stainless steel.

An example drawing note might read material. Stainless steels are alloy steels with iron as the primary constituent and chromium nickel and manganese as principal alloying elements. This micrograin runs parallel to the edge of the ribbon of sheet metal as it comes out of the roller. Stainless steel sheet 16 gauge 304 2b the rolling process also introduces a grain direction in the microstructure of the sheet.

Tour trusted services provider. 2205 stainless steel resists cracking even when faced with a combination of tensile stress corrosive chemicals and heat. Air bending with a v die. As you bend a stainless steel sheet the bend area cold hardens increasing the amount of pressure required to finish the bend.

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. Bending is a forming process in which sheet metal is bent into the desired shape by applying bending stress. Forming blocks and punch sets for domed shapes. Sheet metal forming bags hold any shape workpiece steady while you pound on it with a hammer.

They are called stainless because a chromium or nickel oxide film forms on the sheet surface effectively protecting the steel against corrosion. That prevents the metal from regaining its former shape. 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. It should also be noted that austenitic stainless steels can t be heat treated meaning that cold forming may be your only option.

Thicknesses can vary significantly. In addition elon has specified 3mm thick stainless steel which greatly increases forming tonnages required.
