Product Description

 

Plastic Mould Steel P20 1.2311 Alloy Steel Round Bar tool and die steel
 

1.2311 Tool steel is a type die steel which has been pre-hardened by the "super clean" production process, showing a high degree of purity and excellent uniform structure, excellent polishing and light etching engraving.1.2311 is commonly supplied in the hardened and tempered condition with a supply hardness of approximately 300HB.

 

This steel gives an excellent polished finish and is one of the most widely accepted specifications for machine cut plastic moulds and zinc die casting dies. This grade gives excellent wear resistance but if maximum surface hardness is required for compression moulding plastic dies or similar tools, the steel can be case hardened or nitrided.

Tool and die steel 1.2311 Heat treatment

  • Heat Treatment

    ● Quenching

    Pressurized gas, or interrupted oil to 150-125ºF (66-51ºC).

    For oil, quench until black, at about 900°F (482°C), then cool in still air to 150-125°F (66-51°C).

    ● Tempering

    P20 tool steels are tempered at 482-593°C (900 to 1100°F) for a Rockwell C hardness of 37 to 28.

    ● Annealing

    Annealing for AISI P20 tool steels 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.

     

    Applications of P20 bar and block

    Plastic moulds, die holder, backers, rames for plastic pressure dies, hydro forming mold tools. bolsters, die holders. Also suitable for other applications such as rails, shafts and wear strips.
