Hastelloy X
Description:
The Hastelloy X nickel alloy, with higher iron content, has favorable resistance to oxidation and corrosion combined with excellent creep and rupture strength at temperatures under 900¡æ. In addition to this, Hastelloy alloy X has great fabricability by cold and hot working and good weldability.
High degree of oxidation resistance up to 2200¡ã F
Outstanding high-temperature strength
Easily fabricated including forming and welding
Good ductility after prolonged exposure at high-temperatures
Good resistance to chloride stress-corrosion cracking
Resistant to carburization and nitriding
Develops a protective oxide film that does not spall off
This oxidation resistant alloy can be used for combustor components and other high temperature parts of aircraft engines, for long term use at temperature under 900¡æ and short time use up to 1080¡æ.
Gas turbine engines
Transition ducts
Combustor cans
Spray bars and flame holders
Afterburners, tailpipes, and cabin heaters
Chemical processing retorts, muffles, and tubing
