American Brand P20 Steel Round Bar Plate - China

P20 is an American brand of pre-hardened plastic mold steel.

It is suitable for large and medium-sized precision molds in China.

The factory hardness is HRC30~42 - Pre-hardened plastic mold steel.

Suitable for large and medium-sized precision molds, suitable for long-term production of high-quality plastic molds, and used for large mold bases.

This steel has good machinability and can be generally polished.

In order to increase the mold life to more than 800, 000 mold times, the pre-hardened steel can be quenched and tempered at low temperature.

This is achieved by hardening the fire.

When quenching, first preheat at 500-600℃ for 2-4 hours, then keep it at 850-880℃ for a certain period of time (at least 2 hours), put it in oil and cool it to 50-100℃, then cool the oil in the air.

After quenching, the hardness can reach 50 -52HRC, in order to prevent cracking, low temperature tempering at 200℃ should be carried out immediately.

After tempering, the hardness can remain above 48HRC.
