阐述了研究高韧性耐冲击冷作模具钢(DS钢)的必要性和其成份特点,测定了DS钢的主要性能,并和6CrW2Si及Cr12MoV的强韧性进行了对比。给出了DS钢的最佳热处理工艺及适用范围。
The necessity of the high toughness cold impact die steel (DS steel) and the characteristics of its composition were described. The main properties of the DS steel were determined and compared with the toughness of 6CrW2Si and Cr12MoV. The optimal heat treatment process and application range of DS steel are given.
