Hastelloy® X is a high temperature and corrosion resistant nickel-based solid solution strengthened alloy. This alloy has outstanding resistance to oxidation at high temperatures and possesses exceptional strength at elevated temperatures. This alloy exhibits good formability, weldability, 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.
