Hardness testing for metal stamping parts is conducted using the Rockwell hardness tester. Small, complexly shaped stamping parts can be used to test flat surfaces that are too small to be measured on a standard desktop Rockwell hardness tester. The processing of stamping parts includes cutting, bending, deep drawing, forming, and finishing, among other operations. The materials primarily used for stamping part processing are hot-rolled or cold-rolled (predominantly cold-rolled) metal sheet materials, such as carbon steel plates, alloy steel plates, spring steel plates, galvanized plates, tin-plated plates, stainless steel plates, copper and copper alloy plates, aluminum and aluminum alloy plates, and so on.
