By tools for crushing and grinding it is used for hammers of crushers and jaws for mild grinding and crushing.
P20 tool steel differs from area to area in the different countries.Europeans generally use the DIN spec-DIN EN ISO 4957 standard materials (1.2311 and 1.2312), while in Japan steel industry standard, PX5 is the new standard P20. And the Americas Countries, Grade steel P20 is the most and wide used steel grade material. In China, 3CrM2Mo is the P20 steel grade equivalent, which is in the standard GB/T 1299 tool steel specification.
AISI P20 tool steels are nitrided or carburized. These P20 mold steel materials steels are capable of being machined into complex and large dies and molds. Material P20 steel plate and round bars are mostly used in the carburized condition. The presence of chromium and nickel enhances the toughness and hardness of mold steel P20 grade material.

1,Excellent high temperature toughness
2,Excellent resistance to temper softening and cracking
3,Good hardenability and dimensional stability
4,Excellent tissue uniformity and high isotropy
FORGING:Heating for forging must be done slowly and uniformly. Soak through at F and reheat as often as necessary, stopping work when the temperature drops below 1700 After forging, cool slowly in lime, mica, dry ashes or furnace. D2 should always be annealed after forging.
ANNEALING: Heat slowly to 1550 , hold until entire mass is heated through, and cool slowly in the furnace (40 F per hour) to about 1000 , after which cooling rate may be increased. Suitable precautions must be taken to prevent excessive carburization or decarburization.
STRESS RELIEVING: When desirable to relieve the strains of machining, heat slowly to -1250& , allow to equalize, and then cool in still air (Strain Relieving).
PREHEAT PRIOR TO HARDENING: Preheat slowly to 1350 and hold at this temperature until material is uniformly heated.
HARDENING:After thorough preheating, heat to . Hold the work piece at the hardening temperature until it is completely and uniformly heated.
QUENCHING: D2 steel is an air hardening steel and will develop hardness on cooling in still air. To avoid scaling and prevent decarburization of the work piece surface, controlled atmosphere or vacuum furnaces are recommended. If these furnaces are not available, pack hardening, salt baths or wrapping the piece in stainless steel foil will provide some degree of surface protection in the hardening process. Parts should be allowed to cool to 150F, or to where they can be held in the bare hand, and then temper immediately.
TEMPERING: The tempering temperature may be varied according to the desired hardness. If maximum hardness is desired, tempering should be in the range , but if a lower hardness is acceptable, tempering at F will give the optimum combination of hardness and toughness.
