A Global Leader in Stainless Steel Coil Fabrication Services
Type 321 is a titanium-stabilized chromium-nickel austenitic stainless steel, offering corrosion resistance comparable to 304/304L. This exceptional alloy is designed for usage in temperature ranges between 800-1500˚F. Enhanced with titanium to stabilize against chromium carbide precipitation, Type 321 ensures the formation of titanium carbides. It boasts superior intergranular corrosion resistance, oxidation resistance up to 1500˚F, and excels in creep and stress rupture strength compared to 304/304L. Additionally, it maintains strength at low temperatures and remains non-magnetic when annealed.
