Compared with SKD11, DC53 tool steel has five excellent practical characteristics
Keywords: DC53, SKD11, DC53 tool steel, DC53 toughness, DC53 heat treatment, SKD11 heat treatment
(1) Machinability and good abrasion.
The machinability and the abrasion are better than SKD11, so the tool life is longer and the number of working hours is less.
(2) Advantages in heat treatment
The quench hardening energy is higher than SKD11, so it can improve the defect of insufficient hardness during vacuum heat treatment.
(3) Advantages in online cutting
The high temperature tempering can reduce the residual stress and eliminate the residual austenite, and can prevent the cracking and deformation of the wire cutting process.
(4) Advantages in surface hardening
After surface hardening, the surface hardness is higher than SKD11, so it can improve the mold performance.
(5) Advantages in repair welding operation
Since the preheating and postheating temperatures are lower than SKD11, repair welding operation is relatively simple.
