Inconel - Alloy 625 (UNS N06625)

Alloy 625, a nickel-chromium alloy, is popular for its exceptional corrosion resistance, improved fabricability and high strength from cryogenic temperatures to 1800° F (982° C). Precipitation hardening is not required, as the strength of Alloy 625 is derived from the stiffening effect of columbium and molybdenum on its nickel-chromium matrix. Alloy 625 also offers exceptional resistance to oxidation, carburization and a wide spectrum of severe and corrosive environments.
