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

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.

2738 is in the class of Plastic mold that was develoed from 2311 by adding Nickel 1.0 Selling condition is quench and tempered. So, free from size changing after hardening Hardness range is 280-325 HB (33-37HRC) Suitable for big size plastic mold which thickness over 400 mm High strength with hardening ability .Made of steel that pass degassing process in vacuum result in polishing ability .Can do texturing or EDM .Also, can do surface hardening by various procedure.
