About Alloy 625/INCONEL 625
INCONEL 625 alloy consists of a solid solution alloy of nickel, chromium, and molybdenum with the addition of niobium. When combined with molybdenum, it distorts the alloy's atomic matrix, providing exceptionally high strength in the annealed condition without the need for deliberate strengthening heat treatments. This combination of elements provides excellent resistance to a wide range of exceptionally severe corrosive environments.


Alloy 625 is usually supplied in the annealed condition to provide maximum stability during fabrication and subsequent use. INCONEL 625 alloy has been found to be resistant to both potable water and saltwater or brackish water, where chloride ions can cause pitting and crevice corrosion. As a result, pipes used to collect sour gases have been constructed with solid (or clad) INCONEL 625 alloy and used in seawater heat exchangers in refineries, power plants, and offshore topside services, where this material is often required.
In addition, the alloy has properties that make it an excellent choice for seawater applications, including freedom from localized attack (pitting and crevice corrosion), high corrosion fatigue strength, high tensile strength, and resistance to chloride ion stress corrosion cracking.
INCONEL 625 alloy's excellent and versatile corrosion resistance over a wide range of temperatures and pressures is the primary reason for its widespread acceptance in the chemical processing sector. It is made into various components of plant equipment due to its ease of fabrication.
INCONEL 625 alloy is also widely used in aerospace, automotive, oil extraction, petroleum refining, marine, waste treatment, pulp and paper, and power industries. Recent developments have seen INCONEL 625 alloy used as a weld overlay or co-extruded product for superheater piping and playing an important role in the global growth of municipal waste-to-energy and biofuel production.
