【Abstract】 The composition characteristic of high toughness shock-resistant cold tool steel DS and its main mechanical properties were introduced in this paper. And a comparison of strength and toughness of the steel with those of 6CrW2Si,Cr 12MoV, 5CrSMoWVSi, 6Cr3VSi and YSM was made. The optimum heat treatment process, the scope of application and some typical examples of application for the steel DS were also provided.更多还原
