310S stainless steel (UNS S31008) is an austenitic chromium-nickel alloy designed for extreme high-temperature applications. Its high chromium (24–26%) and nickel (19–22%) content ensures exceptional oxidation resistance, creep strength, and corrosion durability up to 1150°C continuously and 1200°C intermittently238. Below are key details structured for technical reference.
1. Chemical Composition
310S prioritizes oxidation resistance and high-temperature stability through balanced alloying:
