Hastelloy X sheet
A nickel-chromium-molybdenum sheet alloy that keeps its strength and resists oxidation in the hot section of a gas turbine. Double melted and solution treated, it is specified where the metal runs hot for a long time.
- Grade / purity
- Hastelloy X, UNS N06002
- Standard
- SAE AMS 5536R
- Form
- Sheet, 1 mm × 1500 × 2000 mm
Applications
Aerospace engine hardware
Tailpipes, afterburner parts and exhaust components needing oxidation resistance in cyclic service.
Industrial and chemical process
Furnace retorts, muffles, catalyst grids and petrochemical equipment in oxidising or carburising atmospheres.
