Hastelloy X Mesh is a nickel-chromium-iron-molybdenum superalloy with outstanding high temperature strength, oxidation resistance, and fabricability. Hastelloy X Mesh's oxidation resistance is excellent up to 2200° F. Hastelloy X Mesh 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 Mesh is primarily noted for heat and oxidation resistance Hastelloy X Mesh also has good resistance to chloride stress-corrosion cracking, carburization, and excellent resistance to reducing or carburizing atmospheres.

In what forms is Hastelloy X Available at Mega Mex?

Hastelloy X Mesh is one of the most widely used nickel base superalloys for gas turbine engine combustion zone components such as transition ducts, combustor cans, spray bars and flame holders as well as in afterburners, tailpipes and cabin heaters. It is recommended for use in industrial furnace applications because it has unusual resistance to oxidizing, reducing and neutral atmospheres. Hastelloy X is also used in the chemical process industry for retorts, muffles, catalysts support grids, furnace baffles, tubing for pyrolysis operations and flash drier components.

Hastelloy X Mesh 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).
