High temperature alloys

Hastelloy X

 

Hastelloy X is a nickel-chromium-iron-molybdenum alloy with outstanding strength and oxidation resistance at temperatures to 2200°F(1200°C). Provided by the molybdenum content results in high strength in a solid-solution alloy make it having good fabrication characteristics. It is widely used in gas turbines, industrial furnaces, heat-treating equipment and nuclear engineering.
