In the case of proper heat treatment, the strength and toughness are excellent, and the high temperature tempering hardness can reach 62~63HRC.

The toughness of DC53 is more prominent in cold work die steel, and the tools made of DC53 rarely show cracks and cracks, which greatly improves the service life.

The residual stress after wire cutting is tempered at high temperature to reduce the residual stress. Therefore, cracks and deformation after online cutting of large molds and molds that require precision are suppressed.

1.2842 steel is cold work die steel is easy to forge and requires a hardness of 63HRC.
