UNS N08935 is a newly developed super-austenitic alloy for use in highly corrosion wet environments with excellent corrosion resistance in chloride induce service, refineries, petrochemical, chemical plants, biofuels, and other renewable energy applications. This alloy offers higher corrosion resistance and serves a broader temperature range than duplex stainless steels and is a cost-efficient alternative to nickel-based such as UNS N06625 with similar mechanical strength and corrosion performance. The aim of this work is to compare the critical crevice corrosion temperature (CCT) of UNS N08935 with UNS S31254, UNS N08367, UNS N10276 (nickel-based alloy) conducted in a Potentiostatic test in 1 M NaCl according to ASTM G150.
