Product Code : AL-In718-NN-FA
Inconel alloys are oxidation- and corrosion-resistant materials well suited for service in extreme environments subjected to high mechanical loads. When heated, Inconel forms a thick and stable passivating oxide layer protecting the surface from further attack. Inconel retains strength over a wide temperature range, attractive for high-temperature applications where aluminium and steel would succumb to creep as a result of thermally induced crystal vacancies (see Arrhenius equation). Inconel's high temperature strength is developed by solid solution strengthening or precipitation strengthening, depending on the alloy. In age-hardening or precipitation-strengthening varieties, small amounts of niobium combine with nickel to form the intermetallic compound Ni3Nb or gamma double prime (γ″). Gamma prime forms small cubic crystals that inhibit slip and creep effectively at elevated temperatures. The formation of gamma-prime crystals increases over time, especially after three hours of a heat exposure of 850 °C (1,560 °F), and continues to grow after 72 hours of exposure ,Inconel is a registered trademark name of Special Metals Corporation. Inconel 718 is a Gamma Prime strengthened alloy with excellent mechanical properties at elevated temperatures, as well as cryogenic temperatures up to around 1300 F. It is readily worked and can be welded in either the annealed or the age condition. Primary applications include bearing assembly, ballast, casting, step soldering, and radiation shielding.
