Grade 310

Stainless Steel

Grade 310

Grade 310 is an austenitic heat-resisting stainless steel. It is noted for excellent resistance to scaling in continuous service up to 1150°C, and in intermittent heating/cooling conditions up to 1095°C.

This grade is highly resistant to oxidising acids and most common corrosive agents, and in marine conditions it shows little evidence of chloride stress corrosion cracking, outperforming lower alloy grades such as 304 and 316. In particular it has good resistance to hot corrosion in many environments including molten salts.
