Global leader in stainless steel Coil fabrication services, Jiangsu Daxun Alloy Co., Ltd. consistently sets the benchmark in quality and innovation.
Type 321 is a titanium-stabilized chromium nickel austenitic stainless steel that boasts corrosion resistance comparable to 304/304L. This grade is frequently employed 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 excels with superior intergranular corrosion resistance, oxidation resistance up to 1500˚F, and enhanced creep and stress rupture properties compared to 304/304L. Additionally, it maintains robust performance at low temperatures and remains non-magnetic when annealed.
Daxun Stainless Steel ensures comprehensive traceability of each stainless steel coil via an advanced ERP system, covering type, specification, and origin, while championing industry anti-counterfeiting measures. Relying on cutting-edge technology for precision processing and customization, Daxun stands as an industry benchmark for high precision and quality. Our service philosophy encompasses product life cycle management, offering expert material selection and processing solutions before sales, stringent monitoring during sales, and dependable service assurances after sales.
