321 Stainless Steel Bar Description

321(UNS S32100) is a titanium stabilized austenitic stainless steel with good general corrosion resistance. It has good intergranular corrosion resistance at a chromium carbide precipitation temperature of 800-1500 °F(427-816°C). The alloy is resistant to oxidation at 1500 °F(816°C) and has higher creep and stress rupture properties than the 304 and 304L alloys. It also has good low temperature toughness.
