► Features:


1, Good hardness uniformity and polishing property,good machining properties.
2, Good integral machanical performance under high temperature.
3, Good heat-resistance and fatigue-resistance.
4, Pre-hardened to HRC30-36, can be directly used for mould processing, shorten the construction period.
5, High putity and homogeneous structure of China's biggest ESR production base for its strict requirement in the whole process of exploitation, smelting, vacuum degassing, ESR, forging, annealing, inspection.

1, Plastic molds for injection compressing and injection molding.
2, TV cabinets,drum mold of washing machine,etc.
3, Often used in the manufacture of television cabinet, washing machine, refrigerator inner shell, buckets, etc.
4, Main components of overloading mold.



► Delivery condition:


Hot rolled or forged, black surface, pre-hardened or tempering to 28-33HRC/30-35HR.



► 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.


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.
