AISI D3 Cold Worked Tool Steel
The usage of AISI D3:
1. Cutting tools: make cutting tools such as knives, blades, and shears due to its high wear resistance and ability to maintain sharp edges.
2. Dies and punches: use in the manufacturing of dies and punches for stamping, forming, and cutting operations.
3. Cold work tooling: the tool steel is subjected to high levels of stress and wear, such as in the production of molds, dies, and machine parts.

AISI D3 Cold Worked Tool Steel
1: AISI D3 steel introduction
AISI D3 cold work steel, also know as DIN 1.2080 (Werkstoff) and JIS SKD1, is a 12% chrome alloy steel. D3 cold work steelhas very high wear resistance against abrasive and adhesive wear due to the high volume of hard carbides in the steel matrix, medium toughness, dimensionally stable, high compressive strength, not secondary hardenable. Type AISI D3 cold works tool steel is oil-quenched; though small sections can be gas quenched after austenitization using vacuum. As a result, tools made with type D3 cold work tool steel tend to be brittle during hardening.

4: AISI D3 steel mechanical properties
The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as normalized, tempered, QT. If you want to know the properties, kindly contact the salesman.

6: Heat treatment
Isothermal annealing:
- Heat to 800°Cand hold at temperature for 1/2 h to 1 h;
- Furnace cooling to 670°Cand hold at temperature for at least 10 hours;
- Cool by 10°C/h to 630°C;
- Cooling in air.
Maximum hardness:≤240 HB
Stress relieving:
To be carried out after maching before the final heat treatment.
- Heat to 600-650°C, hold for 4-6 hours;
- Cooling in furnace to 300-350°C;
- Cooling in air
Hardening:
- Initial preheating to 350-450°C;
- Second preheating to 650-750°C;
- Heat to hardening temperature 860-890°Cand hold at temperature;
- Cooling in hot oil (40-60°C); oil quenched hardness: 54-59HRC;
Tempering:
Tempering must be carried out within one hour from hardening(warm part) in the range 550-630°Cfor 4-6 hours according to hardness required, the dimensions of the parts and operating conditions.
7: Delivery condition
For hot forged or hot rolled bar, usually the delivery condition is hot forged or rolled, annealed, rough turned.
For hot forged plate, usually the delivery condition is hot forged, annealed, milled surface.
For hot rolled plate, usually the delivery condition is hot rolled, annealed, black surface.
