%X The flow-accelerated-corrosion performance of 20 steel, Q345R steel and 304 stainless steel was investigated in condensed water by using a flow accelerated corrosion test apparatus with three electrodes measurement. Scanning electron microscope (SEM) and energy disperse spectroscopy (EDS) were employed to investigate the thickness, microstructure of corrosion scale. The results showed that the corrosion rates of the test steels were different with a decrease ranking as 20 steel>Q345R steel>304 stainless steel. Their microstructure of corrosion scale had different morphologies. The corrosion scale of Q345R steel was thicker than that of 20steel, but much better of compactness of the former ones.
