DC53 vs SKH-9
DC53 vs SKH-9
We can summary 4 points of different of DC53 vs SKH-9.
No.1.There is 2 Hrc between between DC53 vs SKH-9,The hardness of DC53 hardness should be 60-62HRC,and the hardness of SKH-9 hardness would be 62-64HRC.
No.2 The different of alloy chemical composition，DC53 alloy composition is Ce8Mo2Vsi，but SKH-9 alloy composition is W6Mo5Cr4V2,Different alloy chemical composition will offer different performance of resistance.the resistance of SKH-9 is better than DC53.
No.3 The performance of crack resistance,In cold work tool steel,DC53 is a good choice for crack resistance,and the performance of crack resistance of DC53 is better than SKH-9.

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.
