Effects of austenitizing temperature on microstructure and wear resistance of low-alloy-medium-carbon wear resistant steel

Effects of austenitizing temperature on the microstructure and wear resistance of low-alloy-medium-carbon wear resistant steel were investigated.The results show that the microstructure of the tested steel is the lower bainite/martensite mixed microstructure austenitized at 900 ℃ then interrupted air-cooled,and the preferable match of strength and toughness and optimum wear-resistance can be obtained.
