Rare earths and magnesium are common purifying elements in steel, but it is rarely reported that rare earths and magnesium are added to steel at the same time. In this paper, H13 steel and rare earth magnesium treated H13 steel were prepared respectively by using vacuum induction melting (VIM). After the same forging and heat treatment process, the microstructure and mechanical properties were investigated comparatively. The results show that rare earth magnesium alloy could purify the molten steel. The contents of O and S in H13 steel were significantly reduced. Furthermore, rare earth magnesium alloy promoted the precipitation of carbides in H13 steel and made the carbide distribution finer and more uniform. The tempering mechanical properties indicated that rare earth magnesium alloy improved the hardness, tensile strength and impact energy of H13 steel by different degrees.
