Incoloy 800HT is a nickel-iron-chromium alloy with good strength and excellent resistance to oxidation and carburization in high-temperature atmospheres. It also resists corrosion by many aqueous environments. Incoloy 800HT maintains a stable, austenitic structure during prolonged exposure to high temperatures. Incoloy 800HT is used for process piping, heat exchangers, carburizing equipment, heating-element sheathing and nuclear steam-generator tubing. Standard product forms are round, flats, forging stock, pipe, tube, plate, sheet, strip and wire.
