Incoloy alloy 800H -- UNS N08810  

1. Chemical composition  

Ni - 30.0-35.0;  C - 0.05-0.10;  Si - 1.0 (Max);  Fe - 39.5 (Min);  Cu - 0.75 (Max);  Mn - 1.5 (Max);  Cr - 19.0-23.0;  Al - 0.15-0.60;  S - 0.015 (Max)  

2. Characteristics and applications  

Incoloy 800H and 800HT are dual-validated fe-Ni-Cr alloys with the same chemical composition as 800 alloy, but the creep fracture strength of 800H/800HT alloy is greatly improved by controlling the carbon, aluminum and titanium content and annealing at high temperature.  Low carbon content also enhances its stress fracture resistance, while adding aluminum and iron improves its high temperature strength.  Incoloy 800H and 800 HT are nickel-iron-chromium alloys with high tensile strength due to their aluminum, carbon and titanium components. Incoloy 800H and 800 HT are used in petrochemical, power plants, industrial furnaces, and heat treatment equipment.
