Applications

Tool steel P20+S is ideally suited for the production of moulds where improved machinability is required. Typical applications include bolsters and injection moulds, die holders and zinc die casting dies. P20S is a versatile plastic mould tool steel with high tensile characteristics suitable for many other applications such as shafts and wear strips.


Carbon 0.35-0.45% Chromium 1.80-2.00%
Manganese 1.40-1.60% Molybdenum 0.15-0.25%
Sulphur 0.05-0.10% Silicon 0.30-0.50%
Phosphorous 0.03% max


Heat the P20S component slowly, allow sufficient time for the steel to become heated through. Begin to forge at 1050°C. Do not forge below 930°C reheating if necessary. After forging, cool very slowly.


When dies made from P20S are heavily machined, we recommend stabilising the steel just before finish machining in order to relieve machining strains. Heat up to 460-500°C, soak well and cool in air.


Heat uniformly to 710-740°C.  Soak well, cool slowly in the furnace.


Heat uniformly to 830-870°C until heated through. Quench in oil.


When tempering P20S heat the steel uniformly, soaking at the tempering temperature for at least one hour per 25mm of section. Allow to cool in still air.
