Investigation on influence of the nitrate ion on critical pitting temperature (CPT) of DSS 2205 in 0.6 M NaCl media is the aim of this research. Results revealed that 0.01 M NO3  has negligible effect on CPT, while 0.1 M NO3  causes CPT to shift to a value more than 85 C. Then, a mechanistic approach using pencil electrode was sought based on proposed theory defining CPT as a temperature at which critical current density necessary for passivity (icrit) equals to limiting current density (ilim). Results indicate that nitrate ion increases CPT by increment in ilim and slight decrement in icrit.
