Product Description

 1.2738 718H P20+Ni Special Alloy Mould Forged Steel Block

1. Product Introduction
P20+Ni is specially used for Plastic injection die moulds.  Its characteristics  is right sharpening, photo-etching properties with high purity and good homogeneity. P20+Ni is upgraded version of plastic mold steel.

2. Features
Good polishing and photo-etching properties
Good machinability
High purity and good homogeneity
Uniform hardness
No hardening risks
No hardening costs
Time saving (i.e., no waiting for heat treatment)
Lower tool cost (e.g., no distortion to rectify)
Modifications easily carried out
Can be subsequently nitrided to increase surface wear resistance and locally flame hardened to reduce surface damage.
