Cold Work Tool Steel ASTM D2/1.2379/SKD11/ DC-11, tool steel bar, small MOQ

 

Applications

AISI D2 is recommended for tools requiring very
high wear resistance, combined with moderate
toughness (shock-resistance).
AISI D2 can be supplied in various finishes, including the hot-rolled, pre-machined and fine
machined condition.
AISI D2 is a high-carbon, high-chromium tool steel
alloyed with molybdenum and vanadium characterized by:
- High wear resistance
- High compressive strength
- Good through-hardening properties
- High stability in hardening
- Good resistance to tempering-back.

Introduction

D2 steel is a high carbon - high chromium air hardening tool steel, heat treatable to 60-62 Rc. D2 offers excellent wear and abrasion resistance, due to large volumes of carbides in the microstructure. D2 is widely used in long production cold work applications requiring very high wear resistance and high compression strength. It is machinable in the annealed condition, and, like other air hardening tool steels, exhibits minimal distortion in heat treat. D2 is available in de-carb free rounds, flats, and squares, as well as ground flat stock and drill rod.

Quality Standard

ASTM A681 - 08 Standard Specification for Tool Steels Alloy.

HEAT TREATMENT

FORGING:Heating for forging must be done slowly and uniformly. Soak through at 1850°-1950°F and reheat as often as necessary, stopping work when the temperature drops below 1700°F. After forging, cool slowly in lime, mica, dry ashes or furnace. D2 should always be annealed after forging.

ANNEALING: Heat slowly to 1550°-1600°F, hold until entire mass is heated through, and cool slowly in the furnace (40°F per hour) to about 1000°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 1050°-1250°F, allow to equalize, and then cool in still air (Strain Relieving).

PREHEAT PRIOR TO HARDENING: Preheat slowly to 1350°-1450°F and hold at this temperature until material is uniformly heated.

HARDENING:After thorough preheating, heat to 1800°-1850°F. 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 300°-400°F, but if a lower hardness is acceptable, tempering at 950°F will give the optimum combination of hardness and toughness.
