ATI 22™ alloy is a Ni-Cr-Mo alloy that provides outstanding resistance to pitting, crevice corrosion, intergranular attack, and stress corrosion cracking. The combination of Cr, Ni, Mo, and W provides excellent resistance to a broad range of both oxidizing and reducing environments.

ATI Allegheny Ludlum's plate mill has been producing this alloy since 1987. The alloy is used in a wide range of applications including flue-gas desulfurization systems, bleaching processes in pulp-and-paper plants, waste incinerators, sour gas service, chemical processing plants, pharmaceutical plants, and radioactive waste storage.

The ATI 22™ alloy possesses high strength, good ductility, excellent welding and forming characteristics. The UNS N06022 alloy has been incorporated in ASTM and ASME specifications and is available in a wide range of product forms such as plate, sheet, strip, tube, pipe, bar, billet, and forgings.
