Alloy 625 is an nickel-chromium-molybdenum alloy with an addiction of niobium used for its high strength, excellent fabric ability and outstanding corrosion resistance. With the addition of molybdenum acts with the niobium to stiffen the alloy matrix, providing a high strength without a strengthening heat-treatment. This combination of chemical elements also is responsible for superior resistance to a wide range of corrosive environments of unusual severity as well as to high-temperature effects such as oxidation and carburization.
