Inconel alloys are oxidation-corrosion-resistant materials that are well suited for use in high-pressure, high-heat environments. Inconel, when heated, forms a thick, stable, passivating oxide layer that protects the surface from further attack. Inconel maintains strength over a wide temperature range, making it appealing for high-temperature applications where aluminum and steel would creep due to thermally-induced crystal vacancies. Inconel's high-temperature strength is developed by solid solution strengthening or precipitation hardening, depending on the alloy.
Because of its high temperature resistance and oxidation resistance, Inconel is ideal for use in the oil and gas extraction industries. The oil and gas industries require a superalloy metal, such as Inconel, that can withstand harsh environments and corrosive gases.
