310/310S Stainless Steel Overview
Stainless steel 310/310S is an austenitic heat resistant alloy with excellent resistance to oxidation under mildly cyclic conditions through 2000° F. 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, and low magnetic permeability.
**As you can see below, Grade 310S is a low carbon version of grade 310. 310S is less prone to embrittlement and sensitization in service.
