About 321 Stainless Steel
Alloy 321 (UNS S32100) is a titanium-stabilized stainless steel that offers excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500°F (427 to 816°C). The addition of titanium stabilizes the alloy against chromium carbide formation.
Alloy 321 stainless steel provides superior mechanical properties for high-temperature service, offering higher creep and stress rupture properties than Alloy 304 and 304L. It resists oxidation up to 1500°F (816°C) and maintains good low-temperature toughness.
Alloy 321H (UNS S32109) is the higher carbon (0.04 - 0.10) version developed for enhanced creep resistance and higher strength at temperatures above 1000°F (537°C). The alloy cannot be hardened by heat treatment, only by cold working, and can be easily welded and processed using standard shop fabrication practices.
