Stainless Steel 310S | Stainless Steel 310H | 1.4845 | AISI 310S/H

Alloy Stainless Steel 310 (UNS S31000) with material number 1.4845 is an austenitic stainless steel developed for use in corrosion-resistant applications at high temperatures. The alloy is resistant to oxidation up to 2010oF (1100oC) under mild cyclic conditions.
Due to its high chromium and moderate nickel content, Alloy Stainless Steel 310 is resistant to sulfidation and can also be used in moderate carburizing conditions.

The heavier carburizing atmospheres of thermal process equipment usually require nickel alloys such as 330 (UNS N08330). Alloy 310 can be used in applications involving light oxidation, nitriding, carburizing, and thermal cycling. However, the maximum operating temperature should be reduced. Alloy 310 is also used in cryogenic applications with low magnetic permeability and toughness down to -450oF (-268°C). When heated between 1202 - 1742oF (650 - 950oC), the alloy is susceptible to sigma phase precipitation. A solution annealing treatment at 2012 - 2102oF (1100 - 1150oC) will restore some toughness.
