About UNS S31008 (AISI 310S)

UNS S31008 corresponds to AISI 310S, the low-carbon version of AISI 310. Enhanced with molybdenum, it offers superior resistance to high-temperature oxidation and excellent formability, making it ideal for components requiring both heat endurance and thermal fatigue resistance. It is particularly suited for continuous use up to approximately 1100 °C and in mildly oxidizing cycles up to higher limits.
