Alloy X Nickel Sheet, Coil, Bar & Plate - AMS 5536, 5754, UNS N06002
Hastelloy® X is a high temperature and corrosion resistant nickel-based solid solution strengthened alloy. This alloy has outstanding resistance to oxidation and possesses exceptional strength at elevated temperatures. Molybdenum enables this alloy to be hard, strong, and suitable for welding applications. Alloy X exhibits good formability and machinability.
Alloy X is non-magnetic. It has high strength up to 1500ºF (816ºC) and good oxidation resistance up to 2200ºF (1204ºC). This alloy is especially resistant to carburization and nitriding, conditions which cause failure in some high temperature alloys. It is used extensively in high temperature jet engine and chemical processing applications and is highly resistant to stress corrosion cracking in petrochemical applications. Industrial furnace applications incorporate Alloy X for its resistance to oxidizing and its ability to maintain good ductility after prolonged exposure to extremely high temperatures.
