Description
UNS: N06625
W.Nr.: 2.4856
A nickel-chromium-molybdenum alloy with an addition of niobium that acts with the molybdenum to stiffen the alloy’s matrix and thereby provide high strength without a strengthening heat treatment. The alloy resists a wide range of severely corrosive environments and is especially resistant to pitting and crevice corrosion. Used in chemical processing, aerospace and marine engineering, pollution-control equipment, and nuclear reactors.Our main products involve a wide variety of nickel-base alloy welding sticks, nickel-base alloy power, nickel-base electric welding rods, nickel-base alloy precision castings ,forging and wrought alloys .
