Inconel 625 (Alloy 625), with UNS N06625 and W.Nr. 2.4856, is a highly corrosion-resistant nickel-chromium alloy known for its outstanding strength, weldability, and resistance to a wide range of aggressive environments. It is commonly used in marine, chemical processing, and aerospace applications where high strength and excellent resistance to pitting, crevice corrosion, and oxidation are required.
Inconel 625 offers exceptional resistance to high-temperature oxidation and corrosion in both reducing and oxidizing environments. This makes it a preferred material for demanding applications such as heat exchangers, turbine blades, reactor cores, and exhaust systems in industries like aerospace, chemical, and energy, where superior performance under extreme conditions is crucial.
