Plastic tool steel AISI P20 / DIN 1.2311

Ⅰ.Application

    P20 steel is a low-carbon mould steel , Chromium and Nickel are its main alloying elements .

    P20 steel delivered pre-hardened to approximately 300 B.H , is still capable of being machined and of giving a good polished finish.

    It made specifically to fill the requirements for the machined  cavities and forces used In zinc die casting and plastic molding. 
    Typical applications: Plastic mould, backers, bolsters, die holders. Also suitable for other applications such as rails, shafts and wear strips

    P20S steel delivered pre-hardened to approximately 280/325 H.B.

    Similar to P20, but with a higher sulpher content which provides much improved machinability. This grade is not suitable for polishing or other applications     requiring a fine finish.
    Typical applications: Suitable for large mould frames and bolsters 

    P20N steel delivered pre hardened to approximately 280/325 H.B.

    With added Nickel to ensure consistent hardness through large sections.

    Easy to polish and readily machinable. 
    Typical applications: Used for quality for pressing and injection moulding tools.

Ⅱ. Melting process 

    EAF+LF+VD

Ⅲ. Size range
    Round bars: Dia. 12mm-600mm;
    Flat bars: Thickness: 16mm~300mm; Width: 155mm~800mm;

Ⅳ. Delivery condition
    HR or HF, black surface or peeled/milled surface
