P20 Mold/Mould Steel Features:
1. The steel is pure, suitable for plastic molds that require polishing or etching.
2. It is supplied in a pre-hardened state and can be directly used for mold processing without heat treatment, which shortens the construction period.
3. After forging and rolling, the structure is dense, ultrasonic inspection, no pores, no surface defects.
4. It has good machinability and mirror polishing performance.
