Corrosion of Carbon Steels in Mechanically Stirred Solutions 2.0M H2SO4

The effects of stirring and carbon content on the corrosion of steel in deaerated 2.0M sulfuric acid have been studied. Both increases and decreases in the corrosion rate with the increasing stirring rate were observed: Increased rates with higher carbon content and decreased rates with lower carbon content. Results are explained on the basis of the effect of stirring and carbon content on the cathodic evolution of hydrogen and the effect of the stirring rate on the anodic dissolution process.
