Hastelloy X, also known as Alloy X, UNS N06002, and W.Nr. 2.4665, is a nickel-chromium-iron-molybdenum superalloy. It offers excellent high-temperature strength and oxidation resistance up to 2200°F (1200°C). Hastelloy X is commonly used in gas turbine engine components, industrial furnace applications, and other high-temperature environments where corrosion and heat resistance are crucial. This alloy also exhibits good resistance to carburization and nitriding.
