Excellent resistance to oxidation under mildly cyclic conditions through 1100℃ characterizes 310S. Because of its high chromium and medium nickel contents, 310S has good resistance to sulfidation and other forms of hot corrosion. 310S is widely used in moderately carburizing atmospheres such as encountered in petrochemical environments.
310S is often used at cryogenic temperatures, with excellent toughness to -268℃, and low magnetic permeability. 310S has a machinability rating of 42% relative to AISI B1112 steel. When using high speed steel tooling, this equates to about 70 surface feet per minute. Forming operations should be performed at room temperature whenever possible. Welding with AWS E310-15 electrodes or ER310 bare wire is suggested.
