模具结构中的镶件必须刻印材料型号、硬度以及回火性能。。
All inserts are to be stamped as to the material used in construction, type, hardness and temper.
试验结果表明，该钢在空冷条件下可获得均匀的粒状贝氏体组织，具有良好的耐回火性和较高综合力学性能。
It shows that even granular bainite structure can be obtained in the condition of air quenching. The temper resistance is better and comprehensive mechanical properties of the steel are higher.
