Daido Steel - DC53
High Toughness Cold Work Steel

Delivered Hardness:
Annealed to HB255(max)

Chemical Content(%):
Daido patent material

Comparable Standard:
SKD11 Mod


  • Higher hardness than SKD11 after heat treatment
  • As much as 2 times of toughness as that of SKD11
  • Much improved distribution of carbides and microstructure
  • Better machinability
  • High Temperature tempering can reduce the effect from residual stress thus lower the risk from cracking during W-EDM
  • Suitable for surface treatment

Major Application:

  • Press dies for automobile parts
  • Forming dies
  • Engineered plastic injection moulds
  • Wear plates for plastic injection moulds
