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 superior grade thrives in the 800-1500˚F temperature range and is stabilized against chromium carbide precipitation by the addition of titanium, resulting in the formation of titanium carbides. Type 321 excels in intergranular corrosion resistance, provides oxidation resistance up to 1500˚F, and boasts stronger creep and stress rupture qualities than 304/304L. It also exhibits remarkable strength at low temperatures and remains non-magnetic when annealed.
Daxun Stainless Steel ensures full traceability of each stainless steel coil from the ERP system, detailing type, specification, and origin, while championing industry anti-counterfeiting measures.
