Effect of pre-deformation on corrosion behavior of AISI 304 stainless steel was investigated by electrochmeical measurements, and the influence factors were chacterized by microstructural analysis and electron backscattering diffraction (EBSD). The results of polarization curves and electrochemical impedance spectroscopy indicated that corrosion resistance decreased 15%-20% after 20% pre-deformation. The reason may be due to the martensite transformation and the pile-up of dislocation according to the change of the microstructure. EBSD displays that an increase in grain orientation of austensite and martensite is another factor leading to the decrease of corrosion resistance. Besides corrosion resistance can also be reduced by the increase of the variety and fractions of texture. While corrosion resistance increases because of the increase of low angle boundaries.
