On condition that the surface of 304 stainless steel has formed passive film, we have done research on the impact that the change of concentration of Cl- and Na+, the temperature, pH of Na+, on 304 stainless steel properties. This experiment is preceded studied with electrochemical method. The results show that along with the increase of temperature, pH improves the repairing capacity of passive film on the surface of 304 stainless steel. However, its stability decreases. Meantime, the pitting corrosion will happen become easier, when the repairing capacity of passive film and stability have been weakened because of the concentration of Na+, Cl- increases.
