Stainless Steel 321, 321H
Alloy 321 is a titanium stabilized austenitic stainless steel with excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range. It offers high creep strength and oxidation resistance up to 1500°F (816°C). Alloy 321H features higher carbon content for enhanced creep resistance at temperatures above 1000°F.
