The study of the electrochemical behavior of Alloy 22 (UNS N06022) was carried out in 4 M sodium chloride (NaCl) and 4 M NaCl with sulfate additions of 0.4 M and 0.04 M between 45°C and 105°C with multiple crevice assembly specimens. The passive and crevice corrosion properties of Alloy 22 were investigated in these electrolytes. The susceptibility to corrosion was found to decrease in the presence of sulfate in solution.
