Alloy 625 Nickel-Base Superalloy (UNS N06625)
Alloy 625 is a nonmagnetic, corrosion and oxidation resistant nickel bas alloy. Its outstanding strength and toughness from cryogenic temperatures to 2000˚F are derived from the solid solution effects of niobium and molybdenum in a nickel-chromium matrix. The alloy has excellent fatigue strength and stress corrosion cracking resistance in halide environments. Alloy 625 maintains its corrosion resistance in most seawater applications and provides a high level of resistance in both oxidizing and reducing environments. Applications for this grade include heat shields, gas turbine ducting, chemical plant components and seawater-exposed equipment.
