Stainless Steel 310,310S

Alloy 310 is an austenitic stainless steel that combines excellent high temperature properties with good ductility and weldability. It is typically used for elevated temperature applications as its high chromium and nickel content provide solid corrosion resistance, excellent resistance to oxidation, and superior strength in temperatures up to 2100°F. Due to its high chromium and nickel content, it is superior to 304 or 309 stainless in most environments.
