A Nickel-Chromium-Molybdenum alloy with excellent corrosion resistance in a wide range of corrosive media, being especially resistant to pitting and crevice corrosion. Inconel 625 provides resistance to stress corrosion cracking to chloride ions, making it a favourable choice for sea water applications. The alloy also provides commendable oxidation resistance, with its high strength a result of the stiffening combination of Molybdenum and Niobium on the alloy’s Nickel-Chromium base.
