Durability, solid design, and excellent surface finish are among their many advantages.

GNEE Incoloy 800/800H/800HT Pipe Fitting
Incoloy 800 alloy fittings are an alloy of nickel, iron, and chromium. They maintain their stability and austenitic structure even after prolonged exposure to high temperatures. They exhibit excellent resistance to carburization and oxidation in high-temperature and aqueous environments, while also possessing superior strength. They are typically used in high-temperature applications below 1100°F (593°C).
Incoloy 800H fittings are an iron-nickel-chromium alloy with the same basic composition as Incoloy 800, but with higher creep rupture strength. This enhanced strength is attributed to the mixed composition of carbon, aluminum, and titanium, as well as high-temperature annealing treatment.
It exhibits excellent cold-forming properties, typically associated with nickel-chromium alloys. The grain size results in a pronounced wavy surface texture, known as "orange peel," after multiple cold forming processes. Incoloy 800HT can be welded using standard welding processes.
Both Incoloy 800H and 800HT are commonly used in high-temperature environments exceeding 1100°F (593°C). In corrosive environments and under high-temperature conditions, Incoloy 800H and 800HT are widely used in various fields, including chemical and petrochemical processing, heat treatment equipment, nuclear power plants, and the paper industry.



Gnee Steel offers Incoloy 800/800H/800HT pipe fittings at reasonable prices, customizable to customer needs and based on provided drawings.
