The study of the electrochemical behavior of Alloy 22 was carried out in 4 M NaCl, and 4 M NaCl with sulfate additions of 0.4 and 0.04 M between 45 and 105 °C with Multiple Crevice Assembly (MCA) specimens. The susceptibility to corrosion was found to decrease in the presence of sulfate in solution.
