Product Code : AL-In625-NN-SP
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 Nickel-Chromium Alloy 625 is a highly corrosion and heat resistant alloy with excellent mechanical properties ideal for use in high temperature applications such as heat-treating, chemical processing, and nuclear reactor components. The addition of molybdenum and niobium increases the strength and corrosion resistance of the nickel-chromium base, imparting a stiffening effect that eliminates the need for precipitation-hardening treatments.
