Steel Properties
AISI 310 (UNS S31000) is an austenitic stainless steel developed for use in high temperature corrosion resistant applications. AISI 310 resists oxidation up to 1100°C under mildly cyclic conditions. Because of its high chromium and moderate nickel content, AISI 310 is resistant to sulfidation and can also be used in moderately carburizing atmospheres. AISI 310 can be utilized in slightly oxidizing, nitriding, cementing and thermal cycling applications, albeit, the maximum service temperature must be reduced. AISI 310 also finds usage in cryogenic applications with low magnetic permeability and toughness down to -268°C.
