P20 Steel

P20 SteelP20 tool steel stockholders and suppliers, delivering to the whole of the India. Kohli Iron and Steel store are stockholders and suppliers of P20 tool steel round bar, flat bar and plate. P20 is an alloy tool steel which offers good machine ability even in the hardened and tempered (Brinell 300) condition. This steel gives an excellent polished finish and is one of the most widely accepted specifications for machine cut plastic moulds and casting dies. P20 is often supplied in the hardened and tempered condition ready for machining. In this condition it 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. For better machin ability a higher sulphur version P20S is available. Plastic mould steel pre hardened to 29-33 HRC, uniform hardness distributed evenly in large cross- sections.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 Chemical Composition Carbon 0.40% Silicon 0.40% Manganese 1.00% Chromium 1.20% Molybdenum 0.35%
