Nickel-iron-chromium alloys Incoloy 800, 800H, and 800HT have great resistance to oxidation and carburization when exposed to high temperatures. With the exception of the greater levels of titanium in alloy 800T and carbon in alloy 800H, these nickel steel alloys are equivalent. The earliest of these alloys was Incoloy 800, which was slightly altered to become Incoloy 800H. With this change, the grain size and carbon content were managed to improve the stress rupture properties. To achieve the best high temperature qualities, Incoloy 800HT incorporates further adjustments to the combined titanium and aluminium levels. The dual-certified (800H/HT) nickel alloy combines the qualities of both versions. The Incoloy 800H/HT alloy was developed for structural uses under high temperatures.

Incoloy 800 Fasteners

Nickel-iron-chromium alloys Incoloy 800, 800H, and 800HT have outstanding strength and corrosion resistance. The alloys' exceptional resistance to embrittlement caused by sigma phase precipitation and chloride stress-corrosion cracking is a result of the nickel presence. Corrosion resistance is often very good. Alloys 800H and 800HT exhibit improved creep and stress rupture characteristics when solution annealed. Today, only the dual approved 800H/HT alloy is carried by the majority of vendors, including Duplex Steel.

Incoloy 800 / 800H / 800HT Fasteners have a regulated carbon content in addition to a high-temperature annealing process that results in an average grain size of ASTM 5 or coarser. Incoloy 800 / 800H / 800HT Fasteners have higher creep and rupture strengths are the result of the annealing process and their constrained chemical makeup.
