摘　　要：新开发的新型热精锻模具钢3Cr4Mo2NiVNb热强性明显高于H13，在应用过程中，模具寿命较3Cr2W8V钢高0．5～2倍。The test and application results showed that the strength of new developed pPrecision forging die steel 3Cr4Mo2NiVNb at elevated temperatures was higher than that of die sted H13, and the die life of the new steel increased by 0.5 ~ 2 times as compared with that of steel 3Cr2W8V.

关 键 词：热精锻 模具钢 3Cr4Mo2NiVNb钢 钢
