Inconel 625, a Nickel-Chromium-Molybdenum alloy with low Carbon and Niobium addition, has superior resistance to high temperature effects such as oxidation and carburization as well as to a wide range of corrosive environments of unusual severity, especially resistance to pitting and crevice corrosion. Typical applications for inconel 625 are seawater applications, aerospace components, chemical processing equipment, nuclear water reaction components.
