P20 mould steel plate

AISI P20 Steel Plate Material is a versatile, low-alloy tool steel that is characterized by good toughness at moderate strength levels. The special purpose mold steel P20 steel plate is commonly used for plastic injection mold cavities and tooling and for die casting dies for zinc. P20 mold steel plate material is typically sold in the pre-hardened condition at a hardness of approximately 300 HBW.

Heat Treatment of Tool Steel P20 material

• Stress Relieving

Preheating: Because mold steel P20 steel plate is sold in a pre-hardened condition, hardening heat treatment is not necessary. After machining and intermittently during service, the steel must be thermally stress relieved by heating to 900ºF (482ºC), equalizing and holding for one hour per inch (25.4mm) of thickness, and cooling in air to ambient temperature.

In those rare circumstances where the AISI steel P20 must be re-hardened, the steel must first be annealed prior to hardening.
