Product Details

Inconel 625 (UNS N06625)is a Ni-based deformation superalloy reinforced with Mo-Ni solid solution. is famous for its high strength and outstanding corrosion resistance.  It has excellent resistance to pitting corrosion, crevice corrosion and intercrystalline corrosion. It also has good corrosion resistance to inorganic acids such as nitric acid, phosphoric acid, sulfuric acid and hydrochloric acid in the environment of oxidation and reduction. Alloy 625 Tube can be manufactured by the Seamless/welded process used for Heat exchanger and condenser.
