Product brief introduction

The introduction of the United States P20 carbon Cr-Mo plastic mold steel. Suitable for making plastic molds and die-casting low-melting-point metal mold materials. This steel has good machinability and mirror grinding properties. P20 has been pre-hardened to 285-330HB (30-36HRC), which is equivalent to Swedish 618 German GS-2311. It can be directly used for molding processing, and it has good dimensional stability, pre-hardened steel

Can meet the general purpose requirements, mold life up to 50W module times.

Technical Equipment

3Cr2Mo steel is a universal pre-hardened plastic mold steel,

  Is a widely used plastic mold steel in various countries. Pre-hardened plastic mold steel transformed from P20 of American AISI,

And has been included in the national standard. After machining, it can be machined. It has good machinability and mirror polishing performance. After machining, the cavity deformation and dimensional change are small.

After heat treatment can improve the surface hardness and mold life.
