摘要： Cold tool steel having superior machinability, wear-resistance and minimized heat treatment size-change were obtained by specifying components and contents thereof, especially of C, Cr, Si, V and Mo, not by high-temperature soaking. Further, such prehardened cold tool steals as having excellent machinability even after heat-treatment together with minimum size-change were manufactured by further strictly specifying components, particularly of C, Si, Mn, Mo, V, and by specifying heat-treatment conditions.
