321H Stainless Steel Sheet

321H Stainless Steel Sheet is a high carbon version of 321, with higher strength and creep resistance at high temperatures. S32109 material plate contains Ti and also has good resistance to intergranular corrosion after exposure to chromium carbide precipitation temperature range of 800 – 1500°F. Din 1.4878 stainless steel plate also has good oxidation resistance and can be easily welded using standard welding techniques. We are a alloy 321H supplier with 15+ export experience, contact us for more information and free quote!
