Application: used in making all kinds of bearing ring and rolling elements, like combustion engine, machine tool, and bearings for melting machine; also used for making tools and measuring tools.
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

Forging 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.

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

Stress Relieving 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.
