Jai Ganesh Steels are stockist and suppliers of  P20 steel round bar, flat bar and plate. P20 is an alloy tool steel which offers good machineability even in the hardened and tempered 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 steel  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.

p20 steel grades:

P20 (1.2311) Pre hardened to approximately 300 B.H (65 t.s.i) P20 steel requires no further heat treatment therefore avoiding risk of distortion or cracking. Although pre-hardened P20 is still capable of being machined and of giving a good polished finish.
Applications: Plastic moulds, backers, bolsters, die holders. Also suitable for other applications such as rails, shafts and wear strips

P20 (1.2312) Delivered pre-hardened this material is ready for use at approximately 280/325 H.B. Similar to P20 (1.2311) 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.

Applications: Suitable for large mould frames and bolsters

P20 (1.2738) Delivered pre hardened ready for use at 280/325 H.B. With added Nickel to ensure consistent hardness through large sections. Easy to polish and readyily machinable.
Applications: Used for quality for pressing and injection moulding tools. If the section exceeds 400mm P20 (1.2311) won’t provide a consistent through hardness. Suitable for hard chrome plating and for nitriding.

All our P20 tool steel flats and squares are cut from plate and can be supplied to any dimensions you require.

Principal Design Features This alloy is in the category generally labeled as Mold Steels. Nickel and chromium are the alloying elements for hardness and toughness. This alloy is most often used in the carburized condition.

Applications Typically used for relatively low temperature applications such as die casting dies and injection molds.

Machinability Machinability is relatively good at about 80% that of the W group water hardening steels.

Forming P20 may readily be formed by conventional methods with the alloy in the annealed condition.

Welding This alloy is weldable by conventional methods. Contact the alloy supplier for details and weld procedures.

Heat Treatment For carburizing heat to 1600-1650 F in the carburizing medium. For hardening after carburizing heat to 1500 – 1600 F and hold for 15 minutes then oil quench.

Forging Forge at 2000 F down to 1650 F. Do not forge below 1600 F.

Hot Working See “Forging”.

Cold Working P20 may be readily cold worked by conventional tooling with the alloy in the annealed condition.

Annealing Anneal at 1400 to 1450 F and slow cool in the furnace at a rate of less than 40 F per hour.

Aging Not applicable to this alloy.

Tempering Temper at 900 to 1100 F for a Rockwell C hardness of 37 to 28.

Hardening See “Heat Treating” and “Tempering”.
