The corrosion failure of automobile muffler was analyzed by means of the metallography analysis,XRD and SEM. The results indicted that the chemical compositions and the microstructure of the muffler conformed to specification of SUS409 stainless steel. Based on above analysis,the serious corrosion of automobile muffler was induced by Cl- pitting corrosion and oxygen corrosion.
