The Effects of Erosion-Corrosion on Power Plant Piping
Five steels were tested ranging from a carbon and low alloy steel to a high chromium stainless steel. As in single-phase erosion-corrosion the rate of attack decreased rapidly with increasing alloy. In fact 0.10 percent chromium in the carbon steel reduced the rate to well below that of 0.5 percent Mo steel with 0.005 percent Cr.
