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 2000ºF. 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.

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.
