Alloy X is a nickel-chromium-iron-molybdenum alloy that possesses an exceptional combination of oxidation resistance, formability and high temperature strength. It has also been found to be exceptionally resistant to stress-corrosion cracking in petrochemical applications. Alloy X has excellent resistance to reducing and carburizing atmospheres, making it suitable for furnace components. Due to its high molybdenum content, Alloy X may be subject to catastrophic oxidation at 2200°F.
