310S Stainless Steel Bar - Technical Overview & Specifications
310S is an austenitic stainless steel that combines excellent high temperature performance with good ductility and weldability. It is usually used for high temperature applications because its high chromium and nickel content provides solid corrosion resistance, excellent oxidation resistance and excellent strength at temperatures up to 2100 °F. Due to its high chromium and nickel content, it is superior to 304 or 309 stainless steel in most environments.
