About Incoloy 800-800HT Fasteners
Incoloy 800-800HT fasteners are high-performance, nickel-iron-chromium alloys designed for exceptional strength and corrosion resistance in elevated-temperature applications. The 800HT variant offers superior creep-rupture strength due to tighter control of titanium, aluminum, and carbon content. These fasteners resist oxidation, carburization, and embrittlement, performing reliably up to 1600F. Applications include heat exchangers, furnace components, pressure vessels, and equipment for the petrochemical, chemical, and nuclear power industries. They are available in various forms, such as bolts, nuts, washers, and studs. Incoloy 800HT is a nickel-iron-chromium alloy, and also a modified version of alloy 800. It has high creep-rupture strength.
