This paper presents the results of corrosion studies in two pulp and paper mills employing two corrosion monitoring techniques. (1) linear polarization resistance (LPR) and, (2) electrochemical noise (EN). These on-Iine electrochemical corrosion monitoring techniques were used to evaluate the change in corrosion rate and pitting resistance of Type 316 and 316L stainless steels, as a direct result of chemical change of white water process streams.
