对新型热作模具钢４Ｃｒ２ＮｉＭｏＶ进行了较全面的实验研究。结果表明，该钢的最佳淬火温度范围为９１０～９６０℃，最佳回火温度范围是５８０～６１０℃，从热强性和冲击韧性等因素综合考虑，淬火和回大温度均取上限或下限较佳。
The new hot work die steel 4Cr2NiMoV conducted a more comprehensive experimental study. The results show that the optimal quenching temperature range of the steel is 910-960 ℃ and the optimum tempering temperature range is 580-610 ℃. Considering the factors of thermal strength and impact toughness, Lower limit is better.
