Nickel Alloy 800H, Incoloy® 800H

Incoloy® 800H is a nickel-iron-chromium alloy that is part of the family of 800 series of alloy. Also known as Nickel Alloy 800H, Incoloy 800H has many of the characteristics of the other 800 alloys. These include:

  • Resistance to prolonged exposure to elevated temperatures
  • Excellent resistance to oxidation, sulfidation, and carburization
  • Added Carbon and annealing treatment allows for higher creep and rupture properties above 1100°F (600°C)
  • Resistant to high temperature corrosion
  • Readily machined by standard methods
  • Best joined/welded using products for high temperature situations
  • Resistance to aqueous corrosion at moderate temperatures

Incoloy 800H differs from other 800 alloys in a few ways. First, it has a slightly different chemical composition that includes:

  • Fe 39.5% min
  • Ni 30-35%
  • Cr 19-23%
  • Al+Ti .30-1.20%
  • C .05-.10%

Many companies in a wide range of industries utilize Incoloy 800H and Nickel Alloy 800H for a number of applications, especially those that deal with temperatures about 1100°F (600°C), these include:

  • Industrial furnace components and equipment
  • Petrochemical and chemical processing
  • Equipment for Heat-Treating
  • Pressure vessels and heat exchangers
  • Hydrocarbon cracking
