Inconel® is a family of austenite nickel-chromium-based superalloys. The name is a trademark of Special Metals Corporation, a wholly owned subsidiary of Precision Castparts Corp.

Inconel® alloys are oxidation and corrosion resistant materials well suited for service in extreme environments subjected to pressure and heat. When heated, Inconel® forms a thick, stable, passivating oxide layer protecting the surface from further attack. Inconel retains strength over a wide temperature range, attractive for high temperature applications where aluminum and steel would succumb to creep as a result of thermally induced crystal vacancies. Inconel’s high temperature strength is developed by solid solution strengthening or precipitation strengthening, depending on the alloy.
