Cold Working Tool Steel D3 1.2080 SKD1 wire wod

D3 Tool steel is a cold work steel belong to ASTM A681-1999 Steel Grade standard. D3 Special Steel China Supplier and factory Otai Special Steel Supply D3 Tool steel in Round bar, Plate, Flat bar, Square, Forging Ring and others any shape. And provide cutting, sawing, milled, machining processing.

Applications:

 In general, the applications of D3 tool steel resemble those of D2 but it should be remembered that D3 has better wear resistance of the two steels

and is preferred for such items as shear blades. Owing to its higher wear resistance, D3 tool steel is slightly more difficult to grind than D2.

Mechanical Properties of D3 Cold Work Steel

Physical Properties

Tempering: Temper immediately after quenching. Hold at temperature for 1 hour per inch (25.4 mm) of thickness, 2 hours minimum, then air cool to ambient temperature.

For maximum wear resistance, temper between 300-350°F (149-177°C) for a hardness of 62-63 HRC. For the optimal balance between wear resistance and toughness, temper between 450-500°F (232-260°C). This will produce 58-60 HRC.

To minimize internal stresses in cross sections greater than 6 inches (152.4 mm) and to improve stability in tools that will be EDM'd after heat treatment, soaking times of 4 to 6 hours at the tempering temperature are strongly recommended.

Advantage:

1. High wear resistance

2. High hardenability  

3. Belong to ledeburite steel
