A Global Leader in Stainless Steel Coil Fabrication Services
Type 321 is a titanium-stabilized chromium nickel austenitic stainless steel that offers corrosion resistance comparable to 304/304L. This premium grade thrives in the 800-1500˚F temperature range and is fortified against chromium carbide precipitation through the addition of titanium, leading to the formation of titanium carbides. Type 321 delivers exceptional intergranular corrosion resistance, impressive oxidation resistance up to 1500˚F, and superior creep and stress rupture characteristics compared to 304/304L. It maintains strength at low temperatures and remains non-magnetic when annealed.
At Daxun Stainless Steel, we ensure full traceability for each stainless steel coil via our advanced ERP system, covering type, specification, and origin. We are pioneers in advocating industry anti-counterfeiting measures. Backed by cutting-edge technology, our processing and customization set the industry benchmark with unmatched precision and quality. Our commitment to service involves comprehensive product life cycle management, offering expert material selection and processing solutions pre-sale, meticulous monitoring during sales, and unparalleled service guarantees post-sale.
