Customized High-temperature Nickel-based Alloy Hastelloy X Round Bar
Description:
Hastelloy X is recommended especially for using 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 8,700 hours at 2150 °F (1177°C).
Alloy X also has performed well in jet engine tailpipes, afterburner components, cabin heaters, and other aircraft parts.

Features:
1,RESISTANCE TO OXIDATION
The outstanding oxidation resistance of HASTELLOY X is illustrated below. Tests were conducted by exposing samples to dry air at 2000 Deg. F. and to dry air pressurized to 300 psi at 1750 Deg. F. Two criteria for evaluating oxidation resistance are weight change and depth of corrosion penetration. HASTELLOY X excels in both respects due to the formation of a protective, tenacious oxide film.
2,RESISTANCE TO CARBURIZATION AND NITRIDING
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.
