Abstract：25CrMnSi and 22SiMn2 are two kinds of low alloy wear-resistant steels. In order to study their wear-resistant properties, the wear morphology and microstructure of the two materials were tested and analyzed by sliding wear and impact wear tests. The results show that both the surface and the core of 25CrMnSi are more wear-resistant than 22SiMn2 under the sliding wear condition, but the wear resistance of the core of 25CrMnSi is more different than that of 22SiMn2.Under the condition of impact wear, the wear resistance of 25CrMnSi is relatively poor. Under the two wear conditions, the weight loss of 25CrMnSi is not significantly different, while that of 22SiMn2 under sliding wear conditions is almost 10 times that of impact wear, so 22SiMn2 is more suitable for impact wear conditions.
