Inconel Alloy HX Introduction to Characteristics and Execution Standards

Common Trade Names: Hastelloy X, Nickel X, Alloy X, Nickelvac HX, Nicrofer 4722, Altemp HX, Inconel HX, Pyromet 680.

INCONEL alloy HX (UNS N06002/W.Nr. 2.4665) is a high-temperature, matrix-stiffened, nickel-chromium- iron-molybdenum alloy with outstanding oxidation resistance, and exceptional strength at up to 2200°F (1200°C).

It is used for components such as combustion chambers, afterburners and tail pipes in aircraft and land-based gas turbine engines; for fans, roller hearths and support members in industrial furnaces, and in nuclear engineering.

INCONEL alloy HX is readily fabricated and welded.

Available Product Forms: The alloy is available as rod, bar, billet, extruded section, plate, sheet, strip, wire, pipe and tube.

Specifications:INCONEL alloy HX is designated as UNS N06002/ W.Nr 2.4665. Alloy HX is listed in NACE MR-01-75.
