Hastelloy X is a nickel-chromium-iron-molybdenum solid-solution strengthened superalloy developed for high-temperature combustion and furnace service. With chromium at 20.5-23%, iron at 17-20% and molybdenum at 8-10%, plus cobalt and tungsten additions, the alloy combines outstanding resistance to oxidation and scaling with good forming and welding characteristics. It performs well under continuous high-temperature exposure and thermal cycling, which is why it is specified for gas turbine combustors, flame tubes, transition ducts, furnace muffles and other components in direct contact with hot gas streams. The material is non-magnetic and is supplied in wire, strip, tube, rod and plate.
