Inconel 625 as a nickel based alloy exhibits excellent combined performance, for instance favorable mechanical strength, good corrosion resistance, and satisfactory welding workability. The outstanding mechanical properties are mainly depending upon solid-solution strengthening of molybdenum and niobium in austenitic matrix.
High Performance Alloys for Seawater ServiceOver the years, the nickel-chromium-molybdenum/tungsten alloys have proven to be among the most reliable and cost-effective materials for aggressive seawater applications. Of these, INCONEL® 625 is considered acceptable and the HASTELLOY® C-type alloys (C, C-4, C-276, C-22®) are considered optimum. Nominal Composition Weight %
