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. standard AISI, ASTM, BS, DIN, GB, JIS Size 5-1800mm weight and dimensions according to customer
