DC53 High Pressure Cold Rolled Steel Bar Aisi Standard
Aisi DC53 Cold Rolled Tool Steel Bar High Pressure Steel Pipe For Producing
Cold work DC53 tool steel overcomes the insufficient of SKD11 high temperature tempering hardness and toughness of weakness, DC53 tool steel will fully replace SKD11 tool steel in the field of general and precision mould . Its toughness is 2 times of SKD11, DC53 toughness is more prominent in the cold work die. Made of DC53 tools steel rarely appear crack and craze, greatly improving the service life.
