Global Leader in Stainless Steel Coil Fabrication Services
Type 321 is an advanced, titanium-stabilized chromium nickel austenitic stainless steel, boasting corrosion resistance on par with 304/304L. Particularly effective within the 800-1500˚F temperature range, this grade is fortified against chromium carbide precipitation through titanium addition, resulting in titanium carbides formation. Type 321 not only demonstrates exceptional intergranular corrosion resistance and oxidation resistance up to 1500˚F but also offers enhanced creep and stress rupture qualities over 304/304L. It remains robust at low temperatures and becomes non-magnetic when annealed.
Daxun Stainless Steel ensures comprehensive traceability for each stainless steel coil via an ERP system, documenting type, specification, and origin. As a staunch advocate of industry anti-counterfeiting measures, Daxun leverages leading-edge technology for precision processing and customization, setting industry benchmarks for quality.
