Inconel725(UNS N07725)It is a nickel chromium molybdenum niobium alloy with excellent corrosion resistance. After aging heat treatment, the strength of the alloy can be greatly increased, and the ductility and tensile strength of the alloy can be greatly improved. The alloy also has strong stress corrosion resistance. It is used for pipe fittings, joints and bearings in acid resistant equipment. It is also widely used in marine ship equipment.
