S31008 (310S) Sheet and Plate

A low carbon version of grade 310 that is less prone to embrittlement and sensitization in service.

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.

Combined with its low carbon content, the metal is also effective at resisting embrittlement. The metal is commonly utilized in extreme conditions, such as furnace manufacturing and heat treating equipment.


While both hot and work practices can be applied, cold working is not commonly done on stainless steel 310S; however, it is the only way to work harden the metal. This resistance to cold temperatures is useful in cryogenic environments, as 310S is incredibly tough. However, it can be subject to thermal shock and therefore should be treated and hot-worked with care.
