摘要

In this paper, microstructure, corrosion resistance and wear resistance of low-alloy high-strength wear-resistant steels of NM400 and KN400X were studied. It is found that the wear resistance of these steelsdiffered from each other significantly although their chemical compositions were similar, depending onmicrostructure, grain size and non-metallic inclusions. The results of the tests on corrosion resistanceand wear resistance showed that the KN400X steel had the best performance in both properties. Lowercontent of non-metallic inclusions resulted in more uniform and compact microstructure, which togetherwith better corrosion resistance led to better abrasive wear property.
