321 Stainless Steel Coil or Strip

Product Description   321 stainless steel coil/strip is a titanium-stabilized austenitic stainless steel derived from the 304 family. The addition of ≥5×C% titanium endows the alloy with exceptional resistance to intergranular corrosion, especially after welding or long-term exposure within 450–850 °C. Cold-rolled coils are supplied in 0.2–8 mm thickness and up to 2 000 mm width with 2B/BA finishes, while hot-rolled coils range 1.2–16 mm with No.1 finish; slitting down to 4 mm width and 0.1 mm thickness is possible with ±0.02 mm tolerance. The material meets ASTM A240, EN 1.4541, and UNS S32100 specifications.     Product Advantages High-temperature strength: retains tensile strength ≥ 515 MPa and oxidation resistance up to ~900 °C, outperforming 304/316 grades. Intergranular-corrosion free: titanium preferentially combines with carbon, preventing chromium-carbide precipitation and sensitization during welding or thermal cycling. Excellent weldability & formability: low carbon…
