Applications
P20 plastic mould steel is ideally suited for the production of plastic moulds. Typical applications include die holders, zinc die casting dies, backers, bolsters and injection moulds. The versatility of P20 plastic mould steel with its high tensile characteristics enables uses for a variety of other applications such as shafts, rails and wear strip.
Hardening
Harden from a temperature of 830-880oC followed by oil or air quenching or warm bath quenching 180-220oC. Hardness after quenching is 51 HRC.
Tempering
Tempering temperature: See the data bellow.
Forging
Hot forming temperature: 1050-850oC.
Machinability
Machinability is relatively good at about 80% that of the W group water hardening steels
Corrosion Resistance
This is a steel alloy and it will corrode or rust unless protected.
P3Cr2Mo 1.2311 P20 Delivery condition
