*Brief
A nickel-chromium alloy with good strength and excellent resistance to oxidation and carburization in high-temperature atmospheres. It also resists corrosion by many aqueous environments. The alloy maintains a stable, austenitic structure during prolonged exposure to high temperatures. Used for process piping, heat exchangers, carburizing equipment, heating element sheathing, and nuclear steam-generator tubing.

*Feature
Incoloy 800, like many austenitic stainless steels, can be sensitized, or made susceptible to intergranular attack in some aggressive media, by exposure to the temperature range of (540–760°C).
*Application
For services below 600℃ the use of soft annealed Incoloy 800 is suggested.Incoloy 800 has applications in furnace components and equipment, petrochemical furnace cracker tubes, pigtails and headers, and sheathing for electrical heating element
