Introduction to Alloy 625 (UNS N06625)
Alloy 625 is a renowned nickel-chromium-molybdenum alloy celebrated for its exceptional combination of high strength, outstanding corrosion resistance, and excellent fabricability. As a premier high-temperature alloy and corrosion-resistant material, it performs reliably in severely corrosive environments and under high-stress conditions.
Chemical Composition of Alloy 625
The formidable properties of Alloy 625 stem from its carefully balanced composition, primarily nickel (Ni) supplemented with significant chromium (Cr) for oxidation resistance, molybdenum (Mo) and niobium (Nb) for solid solution strengthening, and high-temperature stability. This composition makes it an ideal nickel-based superalloy for critical applications.
