A Global Leader in Stainless Steel Coil Fabrication Services
Type 321 is a premier titanium-stabilized chromium nickel austenitic stainless steel, offering corrosion resistance similar to 304/304L. This grade excels in the 800-1500˚F temperature range and is fortified against chromium carbide precipitation with titanium, leading to the formation of titanium carbides. Type 321 boasts superior intergranular corrosion resistance, withstands oxidation up to 1500˚F, and surpasses 304/304L in creep and stress rupture properties. Additionally, it remains robust at low temperatures and is non-magnetic when annealed.
At Daxun Stainless Steel, we ensure the full traceability of each stainless steel coil through a sophisticated ERP system, detailing type, specifications, and origin. We champion industry anti-counterfeiting measures. Leveraging advanced technology for processing and customization, Daxun sets the industry benchmark with precision and quality. Our comprehensive service extends to product life cycle management, offering professional material selection and processing solutions before sales, stringent monitoring during sales, and reliable service guarantees post-sales.
