Abstract The effect of the solution temperature and concentration within pits on pitting growth rate of 18-8 austenitic stainless steel has been studied quantitatively under uniform corrosion condition. The practical polarzation curves (PPC) of the sample was measured in the simulated solutions within the pits. The ideal polarization curves and corrosion current densities were obtained by extrapolating the Tafe's lines of the PPC to corrosion potentials. The requirements for repassivation of pitting nuclei were discussed in detail. According to the experimental results, the authors attempted an initial approach to a method for measuring the practical rate of pitting growth.
