Effect of Temperature on Electrochemical Behavior of Stainless Steel in Phosphoric Acid

Abstract:

Electrochemical behavior of 304L and S32304 stainless steel in different temperature and concentration phosphoric acid solution by means of polarization curve and electrochemical impedance spectroscopy. The results showed that with the increase of the phosphoric acid solution temperature, the corrosion voltage and the corrosion current of the stainless steel increase and the polarization resistance and solution resistance decrease. The corrosion-resistant properties of S32304 stainless steel are superior to that of 304L stainless steel.
