An austenitic chromium-nickel grade, Alloy 310S displays excellent oxidation resistance up to 1094°C
Alloy 310S displays excellent resistance to oxidation under mildly cyclic conditions. As a result of its high chromium and nickel content, Alloy 310S has good resistance to sulphidation and other forms of hot corrosion.

Alloy 310S is widely used in moderately carburizing atmospheres such as those encountered in petrochemical environments. The more severely carburizing atmospheres of industrial heat treating furnaces require RA330® or RA333®. Alloy 310S is not suggested for the severe thermal shock of repeated liquid quenching.
The grain size and carbon content meets both 310S and 310H requirements. Alloy 310S is often used at cryogenic temperatures, with excellent toughness and low magnetic permeability. Alloy 310S has good machinability and is readily fabricated.
