摘要
为提高锻模寿命，对锤锻模用钢５ＣｒＮｉＭｏ与４Ｃｒ２ＭｏＶＮｉ进行了力学、热稳定及热疲劳等性能试验，并进行了综合性能研究，４Ｃｒ２ＭｏＶＮｉ钢锻模与５ＣｒＮｉＭｏ钢锻模相比，寿命可提高５％～５０％。
In order to improve forging die life,the tests of
mechanical properties,themal stability and thermal fatigue,etc.are performed for 5CrNiMo and
4Cr2MoVNi steel used for hammer forgie die,and comprehensive properties of them are also
studied,The life of forging die made of 4Cr2MoVNi steel can improve 5%～50%in comparison with
that made of 5CrNiMo steel.
