Hastelloy X Wire is a nickel-chromium-iron-molybdenum superalloy with outstanding high temperature strength, oxidation resistance, and fabricability. Hastelloy X Wire's oxidation resistance is excellent up to 2200° F. Hastelloy X Wire has also been found to be exceptionally resistant to stress-corrosion cracking in petrochemical applications. Matrix stiffening provided by the molybdenum content results in high strength in a solid-solution alloy having good fabrication characteristics. Although Hastelloy X Wire is primarily noted for heat and oxidation resistance Hastelloy X Wire also has good resistance to chloride stress-corrosion cracking, carburization, and excellent resistance to reducing or carburizing atmospheres.

Fabrication with Hastelloy X Wire
Hastelloy X Wire has excellent forming and welding characteristics. It can be forged and, because of its good ductility, can be cold worked. It can be welded by both manual and automatic methods including shielded metal arc, gas tungsten arc, gas metal arc and submerged arc processes. The alloy can also be resistance welded. For hot forming, the alloy should be heated to a starting temperature of 2150° F (1175°C).
