Forged rods of 25 mm in diameter of a test steel accord with high carbon steel H13 were made via vacuum smelting-casting as ingot of 80 mm in diamter, then forged and spheroidizing annealed, which subjected further to solution treatment at 1030, 1040, 1050 and 1060 ^oC respectively for 30 min and then oil quenched, folllowed by tempering at 550 ^oC for 2 h and then air cooling. Herein the effect of post solution treatments on the evolution of microstructure and mechanical property, as well as the hardness and wear resistance of the high-carbon H13 test steel were investigated. The results show that the hardness of the H13 steel is mainly affected by the undissolved carbides and the carbon content in the martensite after solution treatments at 1030, 1040, 1050, 1060 ^oC, while the hardness of the tempered steel is related to the precipitation of secondary carbides from the martensite. With the increase of solution temperature, the precipitation content of secondary carbides in the steel after tempering first increases obviously and then decreases, and then increases slightly, and the maximum value is reached when the solution treatment temperature is 1040 ^oC. This is consistent with the changing trend of hardness and wear resistance of the steel after tempering. After solution treatment at 1040 ^oC, the wear loss of the H13 steel is the least of 2.61 mg, and the wear resistance is the best.
