310S Stainless Steel Composition & High‑Temperature Oxidation Resistance
310S (UNS S31008) is a high‑temperature austenitic stainless steel with 24–26% chromium and 19–22% nickel. Its high chromium‑nickel content provides outstanding oxidation resistance and structural stability during long‑term exposure at 1050–1150°C. The low‑carbon design minimizes sensitization during welding.
310S performs reliably in oxidizing atmospheres, thermal cycling, and mildly sulfur‑containing environments. It is widely used in industrial furnaces, combustion equipment, heat‑treatment fixtures, insulation structures, and high‑temperature transfer components. 310S is supplied as sheets, plates, tubes, bars, and strips. As a high‑temperature oxidation‑resistant alloy, it delivers dependable performance in extreme thermal environments.
