321 Stainless Steel Chemical Composition, Mechanical, Physical Properties By yaang.com

Type 321 Stainless Steel is a stabilized austenitic stainless steel similar to Type 304 Stainless Steel but with a titanium addition of at least five times the carbon content. This titanium addition reduces or prevents carbide precipitation during welding and in 800 - 1500°F service. It also improves the elevated temperature properties of the alloy. Type 321 Stainless Steel provides excellent resistance to oxidation and corrosion and possesses good creep strength. It is used primarily in applications involving continuous and intermittent service temperatures within the carbide precipitation range of 800 - 1500°F.

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.
