Global Leader in Stainless Steel Coil Fabrication Services
Type 321 is a titanium-stabilized chromium nickel austenitic stainless steel that boasts corrosion resistance akin to 304/304L. This grade excels in the 800-1500˚F temperature range and is stabilized against chromium carbide precipitation through titanium additions, leading to the formation of titanium carbides. Type 321 offers unparalleled intergranular corrosion resistance, oxidation resistance up to 1500˚F, and enhanced creep and stress rupture properties compared to 304/304L. Additionally, it remains robust at low temperatures and retains a non-magnetic state when annealed.
Daxun Stainless Steel ensures complete traceability of each stainless steel coil via the ERP system, covering type, specification, and origin, while advocating stringent industry anti-counterfeiting measures. Leveraging advanced technology for processing and customization, Daxun Stainless Steel sets industry benchmarks for precision and quality. Our service model promotes product lifecycle management, delivering expert material selection and processing solutions pre-sale, meticulous monitoring during sales, and comprehensive, worry-free service post-sale.
