Abstract: Austenitic stainless steels are the most popular metallic materials because their relatively low coast, ease of fabrication and reasonable corrosion resistance. The aim of the present research was to clarify the effect of tensile deformation, at ambient temperature, on the corrosion behavior of 304 L stainless steel in 3.5% NaCl solution. Electrochemical kinetic polarization technique was used to investigate the corrosion behavior in NaCl solution. The occurrence of pitting corrosion due to chloride ion attack was also examined by MEB. The experimental results show that corrosion potential increased by increasing the amount of deformation. The specimen deformed at 2.81% showed the best pitting potential or the best corrosion resistance. Increasing the deformation to 10.90% affect negatively the pitting potential. Arrived to 16.36%, the resistance corrosion was affected positively the corrosion resistance.
