P20 Plastic Injection Mold Steel

  P20 mold steel is a mold welding material model, the first is P20, followed by P20H, P20Ni have come out. P20 steel for the production of plastic mold and die casting low melting point metal mold material. This steel has good machinability and mirror grinding performance.

Chinese name P20 mold steel Chinese brand 3Cr2Mo US brand P20 standard AISI-p20 GS-2311 ASSAB-618

Chemical composition:

Carbon C: 0.38

Mn Mn: 1.30

Cr Cr: 1.85

Mo Mo: 0.40

Sulfur S: 0.008


P20 mold steel has been pre-hardened to 285-330HB (30-36HRC), with the Swedish 618 Germany GS-2311 state, can be directly used for mold processing, and has the characteristics of good dimensional stability, pre-hard steel can meet General purpose demand, mold life up to 50W mode.


Hardness uniformity, with good polishing performance and optical etching performance, processing performance

Vacuum degassing refining steel is pure, suitable for polishing or etching processing plastic mold.

Pre-hard state supply, no need for heat treatment can be directly used for mold processing, shorten the duration.

Forging and rolling processing, tissue density, 100% ultrasonic inspection, no pores, eye defects.


Applicable to the TV plastic housing, telephone, drinking fountains, vacuum cleaners and other plastic mold,  washing machine, refrigerator shell, bucket and so on.

Thermoplastic injection mold, extrusion die.

Thermoplastic blow molds.

High Volum mass production A and B mold plate.


Nitriding treatment can be high hardness of the surface layer, nitrided surface hardness of 650-700HV (57-60HRC) die life can reach more than 1 million times, the nitride layer has a dense structure, smooth features, mold release and Anti-wet air and alkaline corrosion resistance.

wet air and alkaline corrosion resistance.
