Abstract
Electrochemical measurements have shown that low Mn (∼︁ 0.2% Mn) modified stainless steels with low (⩽ 1.2% Mo) or no Mo exhibit a higher pitting resistance in NaCl aq (0.005 M up to 2 M NaCl) than the analoguous commercial steels with 1.4% Mn and ∼︁ 2.8% Mo. Microscopic examinations and X‐ray microprobe analysis revealed a correlation between pitting resistance of the steels and the composition of the nonmetallic inclusions as well as of the adjacent matrix. They both differ considerably for the two groups of steels.
