Stainless Steel 321 (AMS 5510/AMS 5645) Technical Data Sheet

Type 321 Stainless Steel is a chromium-nickel stainless steel and with the addition of titanium, type 321 Stainless Steel is resistant to intergranular corrosion. Type 321 Stainless Steel's general corrosion is less than Type 302Stainless Steel.  Type 321 Stainless Steel is used where resistance to intergranular corrosion is required and where the parts are subjected to sustained heating or cooling within the range of 800 to 1500ºF. Type 321 Stainless Steel is commonly used in applications such as exhaust stacks, manifolds and ring collectors.

Typical Mechanical Properties

Availability
Type 321 Stainless Steel is available in Stainless Steel Bars (Round, Hex, Flat, Square), Stainless Steel Tubes and Pipes Stock. 321 Foil (Shim) is available in various thicknesses.
