Product details

1. Introduction of D3 Steel

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


2. Supply Range of D3 Steel

Round bar: Dia:20-600mm Length: <5800(fit 20ft container) >5800mm, 40ft container.

D3 steel round bar Surface: original black, peeled, machined/turned, polished/ grounded/milled/grinded

Steel plate: thickness: 10-600mm width: 30-810mm length: same as above

D3 steel plate Surface: original black, machined/turned, polished/ grounded/milled/grinded

Note: The shipping cost of 40ft container will be higher, so I suggest 20ft container.

6. Heat Treatment of DIN D3 steel

Heat Treatment

D3 tool steel requires hardening and tempering to achieve maximum properties. For maximum accuracy, the parts of D3 tool steel should be stress relieved after roughing operations. Stress should be relieved at 648°C (1200°F) for one hour and cooled slowly.


Annealing

Annealing of D3 tool steel needs to be done in a controlled atmosphere furnace. D3 tool steels should be heated thoroughly to 871°C (1600°F) and cooled slowly at a rate of not more than -6°C (20°F) per hour, until the furnace is black. Then the material should be removed and air cooled.


Tempering

The D3 tool steel should be cooled to room temperature and should be tempered immediately. The parts should be placed in the tempering furnace and increased slowly to the desired tempering temperature. Tempering for 1 hour per inch of thickness is required.


Hardening

D3 tool steel should be heated properly since it is very sensitive to overheating and if not heated maximum hardness cannot be achieved. The work should be directly placed in a furnace preheated to 954°C (1750°F) and soaked for 20-25 minutes, plus 5 minutes per inch of thickness, and then oil-quenched to harden it.
