UNS N08935, is a new alloy with composition 35Ni–30Fe-27Cr-6.5Mo-0.28N, with a very high localized corrosion resistance. Previous results have shown that the alloy has a critical pitting temperature (CPT) above 100°C in the modified electrochemical ASTM G150 method in 3M MgCl2 solution. The results indicate good performance in seawater environments. In the process industry seawater is commonly used, when available, to cool process fluids. Natural seawater at ambient temperature is very corrosive due to for instance microbial activity. This paper presents pitting- and crevice corrosion results for UNS N08935 and UNS N06625 from three months exposure in natural seawater at 30°C and in chlorinated seawater at 45°C, 50°C and 80°C. The results indicate that UNS N08935 could be a stainless steel solution in seawater applications where more expensive nickel base alloys are used today.
