A Global Leader in Stainless Steel Coil Fabrication Services
Type 321 is a titanium-stabilized chromium nickel austenitic stainless steel boasting corrosion resistance comparable to 304/304L. This premium grade excels in high-temperature environments (800-1500˚F), stabilized against chromium carbide precipitation by the addition of titanium, which leads to the formation of robust titanium carbides. Type 321 offers superior intergranular corrosion resistance, exceptional oxidation resistance up to 1500˚F, and enhanced creep and stress rupture qualities compared to 304/304L. Additionally, it maintains strength at low temperatures and remains non-magnetic when annealed.
