Cold Work Die Steels: DC53

GNEE Group office environment

DC53 is a new type of cold work die steel improved on SKD11, and its technical specification is contained in the Japanese Industrial Standard (JIS) G4404, which overcomes the weaknesses of SKD11's high-temperature tempering hardness and toughness, and will fully replace SKD11 in the field of general-purpose and precision molds.

DC53 mold steel practical characteristics:
(1) be cutting, be grinding good: be cutting, be grinding than SKD11 are excellent, so the processing tool life is longer, the number of hours of processing is more provincial.
(2) Advantages in heat treatment: quenching and hardening energy is higher than SKD11, so it can improve the defects of insufficient hardness in vacuum heat treatment.
(3) In the wire cutting processing advantages: by high temperature tempering can reduce the residual stress and eliminate the residual Wolstadt iron, can prevent the wire cutting process to produce cracks, deformation of the trouble.
(4) in the surface hardening treatment of the advantages: surface hardening treatment after the surface hardness than SKD11 high, so can improve mold performance.
(5) Advantages in repair welding operation: Because the preheating and post-heating temperature are lower than SKD11, so the repair welding operation is easier.
