D3 Tool Steel is a high-carbon, high-chromium, oil-hardening tool steel that is characterized by a relatively high attainable hardness and numerous, large, chromium-rich alloy carbides in the microstructure. These carbides provide good resistance to wear from sliding contact with other metals and abrasive materials.

D3 exhibits excellent stability in heat treatment, holding size almost as well as the air-hardening, high-carbon, high-chromium die steels such as D2.


1.For the production of cold dies and punches that are subject to low impact loads, small to medium production volumes, and require high wear resistance.

2. Cold cutting blade for cutting hard and thin metal

3. For drill sleeves, gauges, wire drawing dies, embossing dies, crepe plates, drawing dies, cold extrusion dies and screw roller dies

4. Suitable for the production of large, complex and precision plastic moulds requiring high resistance

Predgrevanje:To minimize distortion and stresses in large or complex tools use a double preheat. Heat at a rate not exceeding 400°F per hour (222°C per hour) to 1200-1250°F (649-677°C) equalize, then heat to 1400-1450°F (760-788°C). For normal tools, use only the first temperature range as a single preheating treatment.

Austenitizing (High Heat): Heat slowly from the preheat to 1700-1750°F (927-954°C)

Gašenje:Za ulje, gasite dok ne pocrni, oko 900°F (482°C), a zatim ohladite na mirnom vazduhu na 150-125°F (66-51°C).

For pressurized gas, the furnace should have a minimum quench pressure of 4 bars. A quench rate of approximately 400°F (222°C) per minute to below 1000°F (538°C) is critical to obtain the desired properties.

Kaljenje: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.

Za maksimalnu otpornost na habanje, temperirajte između 300-350°F (149-177°C) za tvrdoću od 62-63 HRC. Za optimalnu ravnotežu između otpornosti na habanje i žilavosti, kaljenje između 450-500°F (232-260°C). Ovo će proizvesti 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.
