In this paper, the NM1# wear resistant steel produced by a domestic manufacturer and NM2# wear resistant steel produced by a foreign manufacturer are selected to be compared and studied by taking rare earth wear resistant steel NM450F of Baotou Steel as the object of study as well as the corrosion resistance test is carried out with alternate immersion test equipment. The results showed that the loss mass of corrosion was 117.98 g/m2 and corrosion rate was 1.64 g/(m2·h) for rare earth wear resistant steel NM450F of Baotou Steel so that its corrosion resistance was better than that of like products at home and abroad, NM1# and NM2# wear resistant steels. The rust layer of cross section for rare earth wear resistant steel NM450F of Baotou Steel is the thinnest and it appears to be spherical particle with uniform size to spread to matrix and tendency toward corrosion is the smallest.
