    Abstract

    The H13 hot working die steel for die casting was treated by quenching,tempering and secondary hardening to prevent the early-stage failure and improve the service life of mould;meanwhile,strength,plasticity,hardness and impact toughness of the H13 die steel were measured.The results indicate that the second hardening temperature of advanced H13 die steel is 50~70℃ higher than that of conventional one.The H13 die steel exhibits excellent strength-toughness properties and comprehensive service performance after quenching at 1100℃ and secondary tempering at 600℃,where the elongation,yield strength and tensile strength are 8.10%,1335MPa and 1534MPa,respectively.
