This article focuses on the resistence of AISI 304 stainless steel to the pitting corrosion in 1 M acidified chloride solution represented by mixture 0.9M NaCl + 0.1M HCl, at the ambient temperature of 22 ± 3 °C. An evaluation of the pitting corrosion resistance was based on the cyclic potentiodynamic polarization tests performed on three types of steel surfaces: "as received", electropolished and ground + electropolished surfaces. The pitting potentials were determined and compared. Pitted surfaces after potentiodynamic polarization tests were observed by the optical microscope.
