Features

High hardenability, high hardness, high wear resistance, small deformation and toughness. High wear resistance, long life of various types of cold stamping die and cold cutting edge, Roll plate and so on.

For complex and possible deformation of the tool.

Main applications

1) Various types of cold stamping dies, cold cutting blades, screwing plates and the like for long service life.
2) Suitable for complex mold may be deformed.

D3 die steel is improved on the basis of the D2 cold work die steel, conventional heat treatment conditions, the residual austenite almost all decomposition, the general can be omitted cryogenic treatment, the hardness can still maintain a higher toughness.
