800 Alloy
UNS N08800
Trade Name: INCOLOY® Alloy 800

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. 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. Standard product forms are round, flats, forging stock, pipe, tube, plate, sheet, strip, and wire. (Information provided by Special Metals Corporation)
