Japan Datong DAIDO hot die steel DH2F 

 DH2F Introduction 
 Description: Japan Daido Steel Co., Ltd. is a pre-production DH2F hard hot work die steel. A factory pre-hard to HRC37-42.DH2F meet the needs of rapid tooling, so no need to heat treatment for shape complexity, precision tooling and parts, excellent cutting performance, ease of processing carving, mold can be shortened cycle, reduce costs, such as surface treatment and then subjected to further improve the wear resistance and corrosion resistance. Often used in various types of zinc die casting aluminum and magnesium High hard plastic mold, such as: mobile phone shell mold auto lamp mold engine dies. Steel types: pre-hardened mold steel hot steel strengths: good cut, excellent high temperature strength and wear factory state: HRC37-42 

 Specialty 
 Hard to have been pre-37 ~ 41HRC (hardness) without heat treatment. Suitable for complex shape, precision molds and parts. Excellent cutting performance, ease of processing and carved mold. 

 Expected to reduce the mold cycle and reduce costs. If subjected to surface treatment can further improve the wear resistance and corrosion resistance. 

 Use 
 Aluminum, zinc die casting aluminum die casting parts hot extrusion mold stamping molded room punch stripper plate gate sets of various machinery parts plastic mold
