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 niobium combines with molybdenum, it distorts the atomic matrix of the alloy, 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 typically 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, pipelines that 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's properties 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 has excellent and versatile corrosion resistance over a wide range of temperatures and pressures, which is the main reason for its wide acceptance in the chemical processing sector. Due to its ease of fabrication, it is made into various components of factory equipment.
INCONEL 625 alloy is also widely used in aerospace, automotive, oil extraction, oil refining, marine, waste treatment, pulp and paper, and power industries. Recent developments have led to INCONEL 625 alloy being used as a weld overlay or co-extruded product for superheater piping and playing an important role in the growth of municipal waste-to-energy and biofuel production worldwide.
