310S Stainless Steel

310S Stainless Steel has excellent resistance to oxidation under constant temperatures to 2000°F.

Cyclic conditions reduce its oxidation resistance, and a maximum operating temperature of 1900°F is generally recommended if cycling is involved.

Having a lower coefficient of expansion than most 300 stainless steels, 310S may be used in operations involving moderately severe thermal cycling, such as rapid air cooling. It is not usually recommended for liquid quenching. Although 310S has less resistance to absorption of carbon and nitrogen than the higher alloys such as 330 and 333, it is widely used in moderately carburizing atmospheres such as encountered in petro-chem plants.

Because of ts high chromium and medium nickel contents, 310S may be used in atmospheres containng moderate amounts of sulfur.
