310S Stainless Steel

Grade 310S | UNS S31008 | 1.4845

Alloy 310S displays excellent resistance to oxidation under mildly cyclic conditions to 1100°C. Due to its high chromium and medium nickel content, 310S has good resistance to sulfidation and other forms of corrosion.

Alloy 310S is widely used in moderately carburizing atmospheres such as those encountered in petrochemical environments. 310S is not suggested for the severe thermal shock of repeated liquid quenching.
310S is often used at cryogenic temperatures, with excellent toughness to -268°C and low magnetic permeability. 310S has a machinability rating of 42% relative to AISI B1112 steel.

Features of Alloy 310S
◾Oxidation resistance to 2000°F
