7Cr7Mo2VSi Mould Steel Bar
7Cr7Mo2VSi is a high strength and toughness cold work die steel, developed by Shanghai Institute of Materials. The steel in the case of maintaining high toughness, its compressive strength, flexural strength, wear resistance than 65Nb, LD series is the most widely used steel. The steel is mainly used for high impact loads require toughness of the cold die and cold heading die, punching punch such as car leaf spring, standard parts and steel ball cold heading die, etc., also used for stamping die and pull Deep punch.
