P20 Tool Steel


P20 tool steel stockholders and suppliers, carrying to the accomplished of the India. Kohli Adamant are stockholders and suppliers of P20 tool steel annular bar, collapsed bar and plate. P20 is an admixture tool steel which offers acceptable machineability even in the accustomed and choleric (Brinell 300) condition. This steel gives an accomplished able accomplishment and is one of a lot of broadly accustomed blueprint for tool cut artificial moulds and casting dies. P20 is about supplied in the accustomed and choleric action accessible for machining. In this action it gives accomplished chafe attrition but if best apparent acerbity is adapted for compression moulding artificial dies or agnate tools, the steel can be case accustomed or nitrided. For bigger machinability a college sulphur adaptation P20S is available. For bigger through hardenability in beyond sections we aswell activity 1.2738 P20N

Applications

P20 tool steel is ideally suited for the production of plastic moulds. Typical applications include die holders, zinc die casting dies, backers, bolsters and injection moulds. The versatility of P20 tool steel with its high tensile characteristics enables uses for a variety of other applications such as shafts, rails and wear strips.

Manganese 1.00% Chromium 1.20%
Molybdenum 0.35%


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


Heat uniformly to 770-790°C.  Soak well, cool slowly in the furnace.


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.


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


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