Global leader in stainless steel coil fabrication services, Jiangsu Daxun Alloy Co., Ltd. excels in delivering premium quality and innovative solutions.
Type 321 is a titanium-stabilized, chromium-nickel austenitic stainless steel with corrosion resistance comparable to 304/304L. This grade is optimized for use in the 800-1500˚F temperature range and is stabilized against chromium carbide precipitation through titanium addition, leading to the formation of titanium carbides. Type 321 offers superior intergranular corrosion resistance, oxidation resistance up to 1500˚F, and enhanced creep and stress rupture properties compared to 304/304L. Additionally, it retains strength at low temperatures and remains non-magnetic when annealed.
Daxun Stainless Steel ensures complete traceability of each coil through its advanced ERP system, detailing type, specification, and origin. The company champions industry anti-counterfeiting measures. Leveraging cutting-edge processing technology, Daxun sets the benchmark for precision and quality. Their service model includes comprehensive product life cycle management, expert material selection, and processing solutions pre-sale, rigorous monitoring during sale, and reliable after-sales service guarantees.
