Sae Astm Aisi D3 Steel Sheet Plate Mechanical Properties - China

D3 steel, American high carbon, high chromium ledeburite steel.

It has high wear resistance, hardenability, hardenability, toughness, thermal stability, compressive strength, excellent micro-deformation and comprehensive properties, good machining and thermal oxidation resistance, and wide adaptability.

D3 Steel Round Bar Sheet Plate Heat Treatment

Heat Treatment SKD1 steel requires hardening and tempering to achieve maximum properties.

For maximum accuracy, the parts of SKD1 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 SKD1 steel needs to be done in a controlled atmosphere furnace.

D3 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 SKD1 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 SKD1 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.

Properties of D3 Steel

It has high wear resistance, 3 to 4 times higher than the general low alloy tool steel, and the deformation of the quenched body is small.
