CRA Weld Overlay - Dilution and Corrosion Resistance - TWIThe corrosion resistance of alloy 625 weld overlay exhibited a marked drop in corrosion resistance at dilution levels >36%Fe, in the selected test environment of 10w/v% NaCl at pH3. The dilution levels of the marked drop in corrosion resistance were equivalent to the PREN of wrought of alloy 825, in the selected test environment of 10w/v% NaCl

    Corrosion Resistance of Inconel 625 and Austenitic Steel

    The present paper explores the impact of laser cladding parameters on the corrosion behavior of the resulting surface. Powders of Inconel 625 and austenitic Metco 41C steel were deposited on steel substrate. It was confirmed that the level of dilution has profound impact on the corrosion resistance and that dilution has to be minimized. However, the chemical composition of the cladding is Corrosion Resistant Alloys NITRONIC HASTELLOY INCONEL An advanced 7% molybdenum super-austenitic stainless steel offering corrosion resistance in most environments superior to 6% molybdenum super-austenitic stainless steels. In many environments, alloy 27-7MO offers resistance approaching or exceeding that of much more highly alloyed materials such as INCONEL alloys 625, 22 and C276.
