Abstract：The 304 stainless steel strips had experienced multi-pass cold rolling and electroplastic rolling (EPR) on the self-designed electroplastic rolling machine. Properties evolution such as deformation resistance, hardness, tensile strength, and elongation under different rolling ways was studied, and the microstructure was systematically analyzed. The results indicated that the deformation resistance could be remarkably reduced by using high energy pulse current during the rolling process. The strength of strip after each pass electroplastic rolling was lower than that of cold rolled strip, but its elongation was significantly improved, making the deformation ability of material greatly improved. Meanwhile, electroplastic rolling could reduce or cancel the annealing process during the material processing and improve the production efficiency, which had an important engineering significance for finding a clean, environment-friendly, energy saving and efficient production technology.
