1.***9 Cold Work Mould Steel

Applications include:

Typical applications for D2 tool steel are blanking, forming, and trim dies, gages, slitting cutters, wear parts, lamination dies, thread rolling dies, drawing dies, rotary cutting dies, knurls, bending dies, gages, shear blades, burnishing tools, rolls, machine parts, master parts, injection screw and tip components, seaming rolls, extrusion dies, tire shredders, scrap choppers, etc.

Forging:

Heating for forging must be done slowly and uniformly. Soak through at ***0°****0°F and reheat as often as necessary, stopping work when the temperature drops below ***0°F. After forging, cool slowly in lime, mica, dry ashes or furnace. D2 should always be annealed after forging.

Annealing:

Heat slowly to ***0°****0°F, hold until entire mass is heated through, and cool slowly in the furnace (*0°F per hour) to about ***0°F, 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 ***0°****0°F, allow to equalize, and then cool in still air (Strain Relieving).

Preheat prior to hardening:

Preheat slowly to ***0°****0°F and hold at this temperature until material is uniformly heated.

Hardening:

After thorough preheating, heat to ***0°****0°F. Hold the work piece at the hardening temperature until it is completely and uniformly heated.

Quenching:

D2 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 **0F, or to where they can be held in the bare hand, and then temper immediately.

Tempering:

The tempering temperature may be varied
