SS330 (UNS N08330) is an austenitic, nickel-chromium-iron-silicon alloy designed for high-temperature applications up to 2200°F (1200°C). It offers excellent resistance to carburization, oxidation, and thermal shock while maintaining high strength. The alloy remains fully austenitic at all temperatures, is not subject to sigma embrittlement, and cannot be hardened by heat treatment.
