AISI D2 Cold Worked Tool Steel
1: AISI D2 Cold Worked Tool Steel Application
Cutting tool manufacturing: D2 steel is widely used in the manufacture of various cutting tools, including knives, hunting knives, tactical knives, etc. Its high hardness and good wear resistance make the cutting tools able to maintain sharpness for a long time.
Mold making: D2 steel is also used to make various molds, such as stamping molds, forming molds, etc. Its high hardness and high wear resistance make it to maintain stable size and shape over long-term use.
Industrial tools: In addition to cutting tools and molds, D2 steel is also used to make industrial tools, such as scissors, cutters, tools, etc. Its high hardness and good toughness make these tools able to work under heavy load without damage easily.

6: AISI D2 Cold Worked Tool Steel Heating Treatment
AISI D2 tool steels should be preheated very slowly to 815℃ (1500℉) and then temperature can be increased to 1010℃ (1850℉). They are then held at 1010℃ (1850℉) for 20 to 45 minutes and air cooled (air quenched).
Annealing
Annealing of AISI D2 tool steels material should be done at 871℃ to 898℃ (1600℉ to 1650℉) followed by slow furnace cooling at 4.4℃ (40℉) per hour or less.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 AISI D2 grade steel slowly to 1050℉-1250℉, allow to equalize, and then cool in still air (Strain Relieving).
Preheat Prior To Hardening
Preheat slowly to 1350℉-1450℉ and hold at this temperature until grade steel AISI D2 material is uniformly heated.
Hardening
After thorough preheating, heat to 1800℉-1850℉. Hold the work piece at the hardening temperature until it is completely and uniformly heated.
Quenching
AISI D2 tool steel material 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 150℉, or to where they can be held in the bare hand, and then temper immediately.
Tempering
The tempering temperature on material AISI D2 tool steel may be varied according to the desired hardness. AISI D2 tool steels can be tempered at 204℃ (400℉) for achieving Rockwell C hardness of 61 and at 537℃ (1000℉) for a Rockwell C hardness of 54.
