Incoloy 800HT

UNS N08811 is a nickel-iron-chromium alloy specifically designed for high-temperature service with exceptional creep and rupture strength. It is a controlled chemistry version of UNS N08800 (Alloy 800), with tighter limits on carbon (0.06-0.10%), aluminum (0.15-0.60%), and titanium (0.15-0.60%) to optimize high-temperature performance. The alloy maintains an austenitic structure and offers excellent oxidation and carburization resistance, as well as good corrosion resistance

Incoloy 800HT represents the highest-performance member of the Incoloy 800 series of nickel-iron-chromium superalloys. Specifically engineered for maximum creep and rupture strength at elevated temperatures, Alloy 800HT features a tightly controlled chemistry with enhanced aluminum and titanium content combined with a precisely regulated carbon range of 0.06-0.10%. Compared to both standard Alloy 800 and Alloy 800H, this premium grade offers superior high-temperature
