A prediction method for the erosion of mild steel by sand is studied. The prediction method is based on sand erosion results from the summation of erosion by a grain of sand and is proportional to the power law of particle diameter to erosion. Predicted erosion was compared with erosion test results which were done with a sand blast type test apparatus under a sand impact condition of 50 m/s air velocity and at 30° degrees to the test piece. Sieved sand and eleven kinds of logarithmic-normal size distributed commercial sands were used to compare calculated erosion with observed erosion. It is known that predicted erosion has an error of not over 18% for sieved sand and not over 56% for commercial sand.
