DC53 is a high performance cold work die steel, which overcomes the weakness of SKD11 high temperature tempering hardness and toughness.
DC53 exceeds SKD11 die steel in strength and wear resistance. The toughness is twice that of SKD11 die steel, and the toughness of DC53 is more prominent in cold work die steel, and the tools made with DC53 rarely crack and crack, which greatly improves the service life.

DC53 die steel properties:
Softening annealing to a hardness of about 230 HB, heat treatment hardness 60-62HRC.
(1) The machinability and the grinding property are both higher than SKD11**, so the processing tool life is longer and the processing hours are less.
(2) The hardening energy is higher than SKD11, so it can improve the defect of insufficient hardness during vacuum heat treatment.
(3) High temperature tempering can reduce residual stress and prevent the trouble of cracking and deformation caused by wire-cut processing.
(4) The surface hardness after surface hardening is higher than SKD11, so it can improve the performance of the mold.
DC53 die steel use
DC53 cold working die steel is widely used in stamping die, cold working forming die, cold drawing die; Forming roll, punch; Precision stamping die; Precision blanking die for wire cutting and stamping die for various purposes; Tools for plastic deformation of difficult-to-process materials; Die for cold forging, deep drawing and wire rolling; High speed blanking punch, stainless steel plate punch.
