Nickel Alloy: Hastelloy X

Hastelloy Alloy X (UNS N06002)

Penn Stainless inventory now includes Hastelloy Alloy X (UNS N06002)  in sheet, sheet coil, plate, round bar, processed flat bar and tubular products.

General Properties
HASTELLOY X is an extremely versatile nickel alloy resistant to corrosion in all acids and chloride solutions, over wide temperature ranges.

 

Applications

  • Chemical process industry reactors, heat exchangers, columns, and piping.
  • Pharmaceutical industry reactors and dryers.
  • Flue gas desulfurization systems.

 

Specifications

ASTM/ASTE……….. UNS N06002

DIN…………………. .  2.4675

Corrosion Resistance

  • Hastelloy X alloy 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. X alloy exhibits good ductility after prolonged exposure at various temperatures

Weldability

  • Hastelloy X alloy has excellent forming and welding characteristics. It can be forged and, because of its good ductility, can be cold worked. X alloy can be welded by both manual and automatic methods including shielded metal arc (covered electrodes), gas tungsten arc (TIG) and gas metal arc (MIG). The alloy can also be resistance welded.

Heat Treatment

  • Wrought forms of Hastelloy X alloy are furnished in the solution heat-treated condition unless otherwise specified. X alloy is solution heat-treated at 2150°F (1177°C) and rapid cooled. Bright annealed products are cooled in hydrogen
