Alloy 625, also known as Inconel Alloy 625 is a nickel-based superalloy that possesses high strength properties and resistance to elevated temperatures. 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.

Applications for this grade include heat shields, gas turbine ducting, chemical plant components and seawater-exposed equipment.
