Alloy 310/310S 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.
The higher alloyed stainless steels generally have excellent strength at elevated temperatures along with outstanding resistance to creep deformation and environmental attack.
Used in Food Industries, Chemical Industries , Electrielcal Industries, Genrater Industries, Shaft Industries, Cement Industries, Gas Industries, Power Project etc..
