Stainless steel 310S is an austenitic heat resistant alloy with excellent resistance to oxidation under mildly cyclic conditions through 2000 F degree. Its high chromium and nickel contents provide comparable corrosion resistance, superior resistance to oxidation and the retention of a larger fraction of room temperature strength than the common austenitic alloys like Type 304. Stainless 310 is often used at cryogenic temperatures, with excellent toughness to -450 F degree, and low magnetic permeability.
Stainless Steel 310S is used when the application environment involves moist corrodents in a temperature range lower than that which is normally considered "high temperature" service. The lower carbon content of SS 310S does reduce its high temperature strength compared to 310.

Fabrication with Stainless 310/310S
Type 310/310S is readily fabricated by standard commercial procedures. In comparison to carbon steel, stainless steels are tougher and tend to work harden rapidly.
Type 310/310S can be welded using all of the common welding processes.
