Project Description
Hastelloy X (UNS N06002/2.4665)
Hastelloy X (UNS N06002/2.4665) is a nickel-chromium-iron-molybdenum alloy with outstanding strength and oxidation resistance at temperatures to 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.
