When evaluating the best nickel alloy for corrosion resistance, metallurgists often begin with the Pitting Resistance Equivalent Number (PREN). This predictive index quantifies a metal’s resistance to localized pitting in chloride-bearing environments based on its chemical composition. For Ni-Cr-Mo alloys, the standard formula often incorporates tungsten (W) due to its synergistic effect with molybdenum:<\/p>\n
