HASTELLOY X is a wrought nickel base alloy with excellent high temperature strength and oxidation resistance. All of the product forms are excellent in terms of forming and welding. Although HASTELLOY X is primarily noted for heat and oxidation resistance it also has good resistance to chloride stress-corrosion cracking and has good resistance to carburization, excellent resistance to reducing or carburizing atmospheres. Alloy X is one of the most widely used nickel base superalloys for gas turbine engine components.
AMS 5754 has no yield or tensile strength requirements, but it does require a hardness maximum and stress rupture minimums. Strong and Oxidation Resistant to 2200 Deg. F (1200 Deg. C) - HASTELLOY X is a solid solution strengthened grade has good strength and oxidation resistance up to 2200 Deg. F (1200 Deg. C).

Reaiatance to carburization and nitrding
HASTELLOY X also resists carburization and nitriding, two common conditions which often lead to early failure in high-temperature alloys. After 100 hours in petroleum coke, four other materials were completely penetrated by carburization; whereas, Alloy X specimens showed no carburization at all. Of ten materials evaluated in an atmosphere of hydrogen, nitrogen and ammonia at 1100 Deg. F. and 25,00 psi for 64 days, Alloy X had a nitride case less than one-fourth as thick as the closest competitive material without intergranular attack.
HASTELLOY(r) X alloy can be readily cold worked and requires a large amount of forming pressure due its high stiffness characteristic. Solution annealing can be performed after this alloy is cold worked.

HASTELLOY X finds use in petrochemical process equipment and gas turbines in the hot combustor zone sections. Also used for structural components in industrial furnace applications because of the excellent oxidation resistance.
HASTELLOY X is recommended especially for use in furnace applications because it has unusual resistance to oxidizing, reducing, and neutral atmospheres. Furnace rolls made of this alloy were still in good condition after operating for 8700 hours at 2150 Deg. F. Furnace trays, used to support heavy loads, have been exposed to temperatures up to 2300 Deg. F. in an oxidizing atmosphere without bending or warping. Alloy X is equally suitable for use in jet engine tailpipes, afterburner components, turbine blades, nozzle vanes, cabin heaters, and other aircraft parts.
Gas turbine combustion cans and ducting, heat-treating equipment.
Alloy X has wide use in gas turbine engines for combustion zone components such as transition duct, 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. Furnace rolls of this alloy were still in good condition after operating for 8,700 hours at 2150 degrees F (1177 degrees C). HASTELLOY X is also used in the chemical process industry for retorts, muffles, catalyst support grids, furnace baffles, tubing for pyrolysis operations and flash drier components.
Useful Properties for Aircraft and Furnace Parts - HASTELLOY X is recommended especially for use in furnace applications because it has unusual resistance to oxidizing, reducing, and neutral atmospheres. Furnace rolls made of this alloy were still in good condition after operation for 8,700 hours at 2150 Deg. F (1177 Deg. C).
