Virat Special Steels AISI P20+Ni

AISI P20+Ni is specially used for Plastic injection die moulds. The characteristics of a material are right sharpening, photo-etching properties with high purity and good homogeneity. AISI P20+Ni is upgraded version of plastic mold steel 0f 2311, which normally supply in Pre hardened condition. Hardness in as supplied condition 280-320 HB with having uniform hardness. The additional nickel content of 1 % increases through hardening. It has good machinability, suitable for Texturing, fine polishability, adequate corrosion resistance, vacuum-degassed steel.

AISI P20+Ni High Hard ( HXM 24 )

AISI P20+Ni is with High Hardness 360-400 BHN and increase alloy elements to get extra life and outstanding polishing.
