Hastelloy X is a nickel-chromium-iron-molybdenum superalloy. This alloy offers excellent high temperature strength, fabricability, and oxidation resistance. Alloy X has oxidation resistance up to 2200°F. In addition, this nickel steel alloy has been observed to have excellent resistance to stress corrosion cracking in petrochemical applications. The matrix hardness provided by the molybdenum content results in a solid solution alloy with high strength and good fabrication characteristics.
