| High Light | Oxidation Resistance Incoloy 800H ，Carburization Resistance Incoloy 800H ，Nickel Iron Chromium Alloy | ||
Incoloy 800H is a nickel-iron-chromium superalloy specifically designed and optimized for exceptional creep and rupture strength at elevated temperatures. Unlike the standard Incoloy 800 grade, Alloy 800H features a controlled carbon content range of 0.05-0.10%, which provides significantly enhanced mechanical stability and performance in the 593°C to 982°C (1100°F to 1800°F) service temperature range.
This austenitic alloy maintains a stable microstructure even after prolonged high-temperature exposure, offering excellent resistance to oxidation, carburization, and sulfidation. The carefully balanced chemistry of 30-35% nickel and 19-23% chromium ensures outstanding corrosion resistance in both high-temperature and aqueous environments. Alloy 800H is commonly supplied to ASTM B409, ASME SB-409, and ASTM B564 specifications, making it a preferred material for critical applications in petrochemical processing, power generation, and industrial furnace components.
