DC53 heat treatment hardness is higher than SKD11, high temperature (520-530 °C) can reach 62-63HRC high hardness after tempering, DC53 exceeds SKD11 in strength and wear resistance.
The toughness is twice that of SKD11. The toughness of DC53 mold steel is prominent in cold-working die steel. The tools made with DC53 rarely crack and crack, which greatly improves the service life.
The residual stress after the wire cutting process is small, the residual stress is reduced by the high-temperature tempering, and the crack and deformation after the wire cutting process are suppressed.
Machinability and abrasiveness exceed those of SKD11. DC53 mold steel is superior to SKD11 in terms of machinability and abrasiveness. The use of DC53 mold steel increases tool life and reduces machining processes.

Practical features:
DC53 cold work die steel
(1) Machinability and good abrasiveness.
The machinability and the abrasiveness are superior to those of the SKD11, so the processing tool has a long life and the number of processing hours is relatively low.
(2) Advantages of heat treatment
Quench hardening is higher than SKD11, so it can improve the defects of insufficient hardness during vacuum heat treatment.
(3) Advantages of online cutting processing
High-temperature tempering can reduce the residual stress and eliminate the residual Worthfield iron, which can prevent the cracking and deformation of the wire cutting process.
(4) Advantages in surface hardening treatment
The surface hardness after surface hardening is higher than that of SKD11, so the mold performance can be improved.
(5) Advantages in repairing welding operations
Since the preheating and post-heating temperatures are lower than SKD11, the repair welding operation is relatively simple.
