Inconel 625 is a corrosion and oxidation resistant nickel alloy that is used both for its high strength and outstanding aqueous corrosion resistance.

Inconel 625 is a solid-solution matrix-stiffened face-centered-cubic alloy. The alloy may contain carbides, which are inherent in this type of alloy. Carbides that can be found are MC and M6C (rich in nickel, niobium, molybdenum, and carbon). In addition M23C6, a chromium-rich carbide, appears in solution-treated material exposed at lower temperatures. The hardening effect that takes place in the material on exposure in the range centered around 1200°F (See Mechanical Properties section) is due to sluggish precipitation of a nickel-niobium-rich phase, gamma prime. This phase gradually transforms to orthorhombic Ni3Nb when the alloy is heated for long times in the intermediate temperature range. Extensive investigation of the stability of Inconel Alloy 625 following exposure for extended periods in the 1000° to 1800°F temperature range has shown complete absence of embrittling intermetallic phases such as sigma.

The properties of UNS N06625 that make it an excellent choice for sea-water applications are freedom from local attack (pitting and crevice corrosion), high corrosion-fatigue strength, high tensile strength, and resistance to chloride-ion stress-corrosion cracking. It is used as wire rope for mooring cables, propeller blades for motor patrol gunboats, submarine auxiliary propulsion motors, submarine quick disconnect fittings, exhaust ducts for Navy utility boats, sheathing for undersea communication cables, submarine transducer controls, and steam-line bellows. Potential applications are springs, seals, bellows for submerged controls, electrical cable connectors, fasteners, flexure devices, and oceanographic instrument components.

The outstanding and versatile corrosion resistance of Alloy 625 under a wide range of temperatures and pressures is a primary reason for its wide acceptance in the chemical processing field. Because of its ease of fabrication, it is made into a variety of components for plant equipment. Its high strength enables it to be used, for example, in thinner-walled vessels or tubing than possible with other materials, thus improving heat transfer and saving weight. Some applications requiring the combination of strength and corrosion resistance offered by Inconel 625 are bubble caps, tubing, reaction vessels, distillation columns, heat exchangers, transfer piping, and valves.
