AISI P20 Pre-hardened Plastic Mould Steel is a low-alloy tool steel that is characterized by good toughness at moderate strength levels. P20 is typically sold in the pre-hardened condition at a hardness of approximately 300 HBW.

Capable of be machined and of giving a good polish finish.

Stable dimension, minimum distortion 

No further heat treatment avoiding risk of cracking.

APPLICATIONS: commonly used for plastic injection mold cavities and tooling and for die casting dies for zinc. 

Used for plastic moulds, backers, bolsters, die holders.
