Hastelloy® X
Hastelloy X is a nickel-chromium-iron-molybdenum alloy that possesses an exceptional combination of oxidation resistance, fabricability, and high-temperature strength. It has also been found to be exceptionally resistant to stress-corrosion cracking in petrochemical applications.
- Formes courantes : Sheet, Plate, Bar, Pipe, Forgings.
- Caractéristiques principales : Outstanding strength and oxidation resistance up to 2200°F (1200°C).
- Fabricabilité : Good ductility; easily formed and welded.
- Structure : Solid solution strengthened; non-magnetic.
Hastelloy X is the workhorse for hot-section gas turbine components. Unlike many high-strength superalloys which can be brittle or difficult to weld, Alloy X retains good ductility even after prolonged exposure to high temperatures (up to 16,000 hours). It resists oxidizing, reducing, and neutral atmospheres.
Résistance à l'oxydation
Excellent resistance to oxidation, carburization, and nitriding, making it ideal for furnaces and jet engine tailpipes.
Résistance à haute température
Retains significant creep and rupture strength at temperatures where stainless steels would fail structurally (1600°F - 2200°F).
Ease of Fabrication
Known for its forming and welding characteristics. It can be forged and cold-worked, unlike many cast superalloys.
