Global Trailblazer in Stainless Steel Coil Fabrication Services
Type 321 is a titanium-stabilized chromium nickel austenitic stainless steel, boasting corrosion resistance akin to 304/304L. This premium grade excels in the 800-1500˚F temperature range, stabilized against chromium carbide precipitation with the addition of titanium, forming titanium carbides. Type 321 stands out with superior intergranular corrosion resistance, oxidation resistance up to 1500˚F, and exceptional creep and stress rupture properties compared to 304/304L. It remains robust at low temperatures and non-magnetic when annealed.
Daxun Stainless Steel achieves comprehensive traceability for each stainless steel coil via its ERP system, detailing type, specification, and origin, and actively champions anti-counterfeiting in the industry.
