Nickel Alloy 800HT Incoloy 800HT

Another member of the 800 alloy family is Incoloy 800HT. Also sold as Nickel Alloy 800HT, this nickel-iron-chromium alloy, has many of the same characteristics as other members of the 800 alloy grouping. Incoloy 800HT has roughly the same chemical composition as Incoloy 800H, differing only slightly in carbon, aluminum, and titanium levels.

• Fe 39.5% min

• Ni 30-35%

• Cr 19-23%

• Al+Ti .85-1.20%

• C .06-.10%

A good way to understand the difference between 800HT and 800H is that the chemical composition of Incoloy 800HT will always be within the limits of Incoloy 800H, but the reverse is not true.

Incoloy 800HT is known for many of the same outstanding characteristics as Incoloy 800H including:

• Excellent resistance to oxidation, sulfidation, and carburization

• Higher creep and rupture properties for high temperature situations above 1100°F (600°C)

• Resistant to high temperature corrosion and prolonged exposure

• Readily machined by standard methods

• Resistance to aqueous corrosion at moderate temperatures

Users of Incoloy 800HT and Nickel Alloy 800HT use the alloy for a wide range of high-temperature applications including:

• Hydrocarbon cracking

• Industrial furnace and boiler components and equipment

• Equipment for Heat-Treating

• Pressure vessels and heat exchangers

• Chemical and Petrochemical processing
