Abstract：The forming cause of crack in washing machine outer barrel made from 430 ferrite stainless steel is studied by analyzing chemical composition， metallographic structure and EDS. The results show that the crack forming is due to high nitrogen content in steel, which leads to more secondphases in grain boundary. The reason producing high nitrogen content is also analyzed.
