INCONEL nickel-chromium alloy 625 is used for its high strength, excellent fabricability , and out-standing corrosion resistance. Strength of INCONEL alloy 625 is derived from the stiffening effect of molybdenum and niobium on its nickel-chromium matrix; thus precipitation-hardening treatments are not required.
