What is 321 Cold Rolled Stainless Steel Coil?
321 cold rolled stainless steel coil is a titanium-stabilized austenitic stainless steel (UNS S32100 / EN 1.4541 / JIS SUS321), containing approximately 0.7% titanium to suppress intergranular corrosion. The cold rolling process ensures a high-precision surface finish, making it an ideal material for welded structures operating at elevated temperatures between 400°C and 650°C.

321 SS Bright Annealed Finish Coil Advantages
Stainless Steel 321 Polished Coils Surface Treatment
🔹2B surface (Ra≤0.8μm): smooth without oxide scale, suitable for food equipment, medical equipment (easy to clean)
🔹BA surface (Ra≤0.2μm): mirror-like gloss, meeting the surface requirements of high-end decoration or precision instruments.
🔹Cold Rolled 321 Stainless Steel Coil has no risk of sensitization when used for a long time at 650℃, and the weight gain due to oxidation is ≤10g/m², which is 20% higher than 304 stainless steel in terms of high temperature oxidation resistance, meeting the load-bearing requirements of industrial furnace pipelines and heat treatment basket brackets.
