Incoloy 800HT are nickel-iron-chromium alloys with excellent strength and good resistance to rust and carburization in high temperature exposure.ncoloy 800, 800H, and 800HT are nickel-iron-chromium alloys with excellent strength and good resistance to rust and carburization in high temperature exposure.
Nickel Alloy Incoloy 800HT Pipe
Incoloy 800 HT is composed of more aluminum and titanium. This gives 800 HT even greater resistance to high temperatures. Incoloy 800 HT is recommended for temperatures exceeding 1100° F, often in instances where stainless steels are subject to crack and creep. The Incoloy alloys are commonly used in high temperature environments, such as industrial furnaces, chemical and nuclear vessels, and heat-treating equipment. Incoloy 800 HT is dually certified.
