Inconel 625 is a nickel chromium which is generally applied for high toughness environment, magnificent fabricability and exceptional corrosion resistance. Inconel alloy 625 strength is derived from stiffening reaction of molybdenum and niobium on nickel-chromium, thus precipitation hardening treatments are not required. This consolidation of elements also is responsible for exceptional resistance to a wide range of corrosive environments. The strength of Incoloy 625 that make it a superior choice for sea-water applications, high corrosion fatigue strength, good tensile strength and support to chloride-ion stress-corrosion cracking.
