　　Q1:how can the heat treatment hardness of H13 die steel reach hrc58

 

　　H13属于热作模具钢，主要考虑其高温下韧性和强度的匹配较好。不知朋友要用H13做什么用，为什么要把硬度设成这么高，但可以肯定的是，如果H13只淬火而不回火，硬度可能会达到你的要求，但于室温工作时，如果工作温度升高，其硬度必然下降，况且不回火的H13很脆的，很容易裂掉。所以我认为你的选材本身就有问题。

 

　　H13 is a hot working die steel,mainly considering its good matching of toughness and strength at high temperature.I don't know what my friends want to do with H13 and why they want to set the hardness so high,but it is certain that if H13 is only quenched without tempering,the hardness may meet your requirements,but it is limited to working at room temperature.If the working temperature increases,its hardness will inevitably decrease.Moreover,H13 without tempering is very brittle and easy to crack.So I think your material selection itself has a problem.
