P20 steel is the plastic die steel of medium-carbon Cr-Mo series imported from the United States. The steel has good machinability and mirror grinding performance, is suitable to make plastic molds, and mold materials for die-casting low-melting-point metal.
Steel Grade | C | Si | Mn | P | S | Cr | Mo | Cu |
P20 | 0.28-0.40 | 0.20-0.80 | 0.60-1.00 | ≤0.030 | ≤0.030 | 1.40-2.00 | 0.30-0.55 | ≤0.25 |
Vacuum degassing and refining process make pure steel quality, suitable for plastic molds that require polishing or etching.
Supplied in pre-hardened state, it can be directly used for mold processing without further heat treatment, shortening the production period.
The microstructure is dense with forging and rolling. No pores and pinhole defects against 100% ultrasonic inspection.

Thermoplastic injection molds, extrusion molds.
Thermoplastic blow molds.
Main components of heavy-duty molds.
Cold-formed structural parts.
Commonly used in the manufacture of TV cabinet, washing machines, refrigerator inner shells, buckets, etc.
Car bumper mold.
