A Global Leader in Stainless Steel Coil Fabrication Services
Type 321 is a titanium-stabilized chromium nickel austenitic stainless steel that boasts corrosion resistance comparable to 304/304L. This superior grade is ideally utilized within the 800-1500˚F temperature range and is fortified against chromium carbide precipitation through the addition of titanium, which precipitates as titanium carbides. Type 321 offers exceptional intergranular corrosion resistance, withstands oxidation up to 1500˚F, and exhibits enhanced creep and stress rupture properties compared to 304/304L. Additionally, it maintains strength at low temperatures and remains non-magnetic when annealed.
