Abstract: High-Mo die casting die steel 4Cr5Mo2V is the domestically made steel similar to the advanced imported die casting die steel Dievar. Based on the previous research of this type of steel, the influence of chemical composition on the microstructure and properties of this type of die casting die steel, the best heat treatment process selection, and the evolution mechanism of carbide precipitation during annealing, quenching and tempering were summarized. At the same time, it was suggested that further research should be carried out on the mechanism of carbide interaction and microalloying mechanism.

Key words: die casting die steel, Dievar steel, 4Cr5Mo2V steel, carbide evolution, heat treatment
