Effects of Milling Parameters on the Corrosion Resistance of Type 304 Austenitic Stainless Steel

The effects of milling parameters on the corrosion behavior of 304 austenitic stainless steel were investigated using electrochemical potentiodynamic polarization tests. The results indicated that the general corrosion resistance of the material after milling was superior to that of the original material. The pitting resistance decreased as the feed rate and cutting speed increased, a max reduction of 138 mV in pitting potential was observed for varying milling parameters, which indicates the intensive influence of milling parameters on the corrosion resistance of austenitic stainless steel.
