    HEAT TREATMENT of 1.2311 P20 PDS-3 3CR2Mo


    Forging: P20 plastic mould steel are forged at 1093°C (2000°F) down to 899°C (1650°F). Forging below 871°C (1600°F) is not recommended for these steels.


    Annealing: Annealing takes place at 760-788°C (1400 to 1450°F) and then the steels are cooled slowly in the furnace at a temperature less than 4°C (40°F) per hour.


    Stress Relieving: When dies are heavily machined, we recommend stabilising just before finish machining in order to relieve machining strains. Heat to 460-500°C. Soak well and allow to cool in the air.


    Hardening: Heat the steel uniformly to 820-840°C until heated through. Quench in oil.


    Tempering: Heat uniformly and soak at the tempering temperature for at least one hour per 25mm of section. Allow to cool in still air.


    Carburising / Case Hardening: Tools produced from may be case hardened, which can achieve a surface hardness of 55 to 59 HRc.


    Tufftriding: At 570ºC tufftriding of 1.2311 P20 PDS-3 3CR2Mo tool steel will give a surface hardness of approximately 700HV. Allowing two hours treatment the surface hard layer will be approximately 0.1mm.


    Hard Chromium Plating: To avoid hydrogen embrittlement P20 should be tempered for 4 hours at 180°C for 4 hours after hard chromium plating


    Flame / Induction Hardening: Flame or induction hardening of P20 will achieve a hardness of 50 to 55HRc. Air cooling is preferable, though smaller components may require forced cooling. Temper immediately after hardening.


    Cold Working:P20 plastic mould steel are capable of being readily cold worked by using conventional tooling methods with the alloy in the annealed condition.


    Welding: Conventional methods are used for welding of P20 plastic mould steel.


    Forming: P20 plastic mould steel can be readily formed by conventional methods in the annealed condition.


    Machinability: P20 plastic mould steel have excellent machinability at about 80% that of water hardening steels.
