Applications UNS N06625:
UNS N06625 is a nickel-chromium-molybdenum alloy with niobium added. This provides 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.
