The Effect of Cr on the Electrochemical Corrosion of High Mn Steel in a Sweet Environment
Source abstract
Abstract
The corrosion property of three different steels is evaluated in a sweet environment with respect to Mn content and Cr addition. The result shows that high Mn content in steel suppresses the formation of protective FeCO 3 scale and it decreases its corrosion resistance in sweet environment. However, addition of 3 wt% Cr improves the stability of the corrosion product formed on high Mn steel. As the immersion time increases, the barrier effect of scale formed on high Mn steel containing 3 wt% Cr becomes better by the formation of both (Cr,Fe)-hydroxide layer and Cr-rich Fe carbonate layer.
