Special Metals INCONEL® Alloy HX
Categories:	Metal; Nonferrous Metal; Nickel Alloy; Superalloy
Material Notes:	A nickel-chromium-iron-molybdenum alloy with outstanding strength and oxidation resistance at temperatures to 2200°F (1200°C). Matrix stiffening provided by the molybdenum content results in high strength in a solid-solution alloy having good fabrication characteristics. Used in gas turbines, industrial furnaces, heat-treating equipment, and nuclear engineering. Standard product forms are round, extruded section, flats, forging stock, plate, sheet, strip, and wire. Data provided by the manufacturer, Special Metals.
