Abstract: Microstructure, mechanical properties and wear behavior of an independently developed W-Mo-V modified H13 die steel (indicated as HBJ3 steel) after tempering at 500, 550 and 600 ℃ were studied and compared with H13 steel. The results show that the hardness and tensile strength of the HBJ3 steel after tempering at 600 ℃ are obviously increased compared with that of the H13 steel. After tempered at 500, 550 and 600 ℃, the friction coefficient and wear rate of the HBJ3 steel are all lower than those of the H13 steel, in which the wear rate is decreased by 38%, 58% and 64%, respectively. The wear mechanism of the HBJ3 steel is mainly oxidation wear and abrasive wear, while the H13 steel also has the mechanism of peeling wear.
