Global Leader in Stainless Steel Coil Fabrication Services
Type 321 is a premium titanium-stabilized chromium-nickel austenitic stainless steel. It boasts corrosion resistance akin to 304/304L and is ideal for use within the 800-1500˚F temperature range. Enhanced with titanium, it is adept at preventing chromium carbide precipitation, forming titanium carbides instead. Type 321 stands out with superior intergranular corrosion resistance, exceptional oxidation resistance up to 1500˚F, and enhanced creep and stress rupture properties compared to 304/304L. Additionally, it maintains strength at low temperatures and remains non-magnetic when annealed.
Daxun Stainless Steel ensures comprehensive traceability of every stainless steel coil via an advanced ERP system, covering type, specification, and origin.
