The high carbon medium manganese steel is with the La+Ce complex processing. The occurrence state and change rules of storage for La and Ce in high carbon medium manganese steel as well as the effects of La and Ce on sulfides, oxide inclusions, microstructure, static compression hardening efficiency and impact wear property are systematically studied through the composition analysis, microstructure observation, 30% static compression, impact wear test and theoretical analysis. The study results showed that the contents of solid solution La and Ce in steel could not be increased by adding into a large amount of La and Ce as well as they all remained below 0.003 5% for high carbon medium manganese steel. The 30% static compression hardening efficiency at room temperature can be improved with La and Ce, from 94.4% without La and Ce to 96.68%~108.2% with La and Ce; impact wear resistance of sample is improved with La and Ce as well as relative wear resistance is increased by 1.057 0~1.606 9 times when impact load is 2 J and 1.080 4~1.374 1 times when impact load is 5 J. Under the experimental conditions, the optimal amount of La+Ce added into high carbon medium manganese steel is 0.20%~0.25%.
