Grade DC53 steel is a new type of
cold work die steel for the improvement of SKD11 steel. Its technical specifications are contained in Japanese Industrial Standard (JIS) G4404. It overcomes the weakness of SKD11 high temperature tempering hardness and toughness, and will completely replace SKD11 in the field of general and precision molds.
DC53 Steel Properties
(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 in 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.
DC53 Mold Steel Application
