Good Toughness Cold Work Tool Steel Flat Bar DC53 For Cold Forming Die
Super Good Quality High Toughness DC53 Cold Work Tool Steel Flat Bar
DC53 is a cold work tool steel, it's improved by SKD11.
It overcomes the SKD11 high temperature tempering hardness and lack of toughness weaknesses, will be in the field of general and precision molds SKD11 fully replace the high strength and toughness of common cold die steel.

About DC53 cold wotk tool steel
In the case of appropriate heat treatment strength, toughness are excellent, high temperature tempering hardness of up to 62 ~ 63HRC.
The ductility of DC53 is more prominent in the cold work die steel, tools made with DC53 rarely crack and crack, greatly improving the service life.
Residual stress after wire cutting, high temperature tempering to reduce the residual stress. Therefore, large-scale molds and precision molds required on-line cutting cracks and deformations are suppressed.
Main usages
1. Blanking die, cold forming die, cold-drawing die
2. Forming roll, punch
3. Precision stamping die.
4. Wire cutting precision punching die and a variety of uses stamping die.
5. Difficult to plastic deformation of materials processing tools.
6. Cold forging, deep drawing and rolling mold.
Main features
(1) Was machinability, was grinding good. Was machinability, were grinding than SKD11 excellent, so the longer life of processing tools, processing hours more provinces.
(2) The Advantages in Heat Treatment Quenching and hardening can be higher than SKD11, so the defects of insufficient hardness in vacuum heat treatment can be improved.
(3) The advantages of online cutting process By high-temperature tempering can reduce residual stress and eliminate residual austenite, wire cutting can prevent cracking, deformation problems.
(4) Advantages in the surface hardening treatment The surface hardness after the surface hardening treatment is higher than that of the SKD11, thereby improving the mold performance.
(5) Advantages in repairing welding work Because the preheating and post-heating temperatures are lower than those in SKD11, it is easier to repair the welding work. Features: General cold work die steel, high hardness, high toughness DC53 die steel
