H13 hot-working die steel was treated with adding of rare earth Ce element. The isotropic performance of H13 steel was studied along with isothermal spheroidizing heat treatment. The impact toughness was tested by JBN-300 pendulum impact test machine, and the micro-hardness was measured by TESTER HV-1000 MICROHARDNESS micro hardness tester. The results showed that with the increase of Ce, the transverse and longitudinal mechanical properties of H13 steel tend to firstly increased and then decreased, when Ce content was 0.05%, isotropic performance of H13 die steel significantly increased to the maximum value of 91.10%. Ce has little effect on the micro-hardness. The isotropic performance of H13 die steel increases differently by adding Ce. © 2016, Editorial Office of Journal of the Chinese Society of Rare Earths.
