The effect of potassium chlorate （KClO3） as oxidants on pickling behaviour in HCl-based electrolyte and the surface quality of original hot-rolled and blasted 430 stainless steel （430-SS） were studied,by means of weight-loss tests,microstructure analyses,potentiodynamic polarization curves and electrochemical impedance spectroscopy measurements. The results showed significantly accelerated pickling process for 430-SS happened by adding KClO3 through enhanced cathodic reaction rate and reduced Rt,with pitting corrosion when excess KClO3 was added. KClO3 is a proper oxidant for pickling in HCl-based electrolyte of 430-SS,with reasonable addition of 1%.
