9. About Us
Forging of D3 Cold Work Tool Steel
Pre-heat at 900-950°C then raise temperature to 1050-1100°C. Soak until uniformly heated. D3 tool steel is relatively hard at elevated temperature. Therefore, initial hammer blows must be light and the temperature must not be allowed to fall below 1020°C until the metal begins to flow. Final forging should not be done below 900°C.
Heat Treatment of D3 Cold Work 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
Heat D3 tool steels uniformly to 850-870°C, soak thoroughly, then slow furnace cool at a rate of not more than 25°C per hour to 650°C. The parts may then be air cooled. This should result in a maximum hardness of brinell 248.
Tempering
The D3 cold work 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 is extremely sensitive to overheating during hardening - do not overheat.
Pre heat slowly to 800-850°C, the raise rapidly to 950-970°C and soak until completely equalised. Quench in oil.
D3 SKD1 1.2080 Cr12 Tool Steel is a high carbon, high chromium, oilhardening tool steel thatis characterized by a relatively high attainable hardness and numerous, large, chromium rich alloy carbides in the microstructure. These carbides providegood resistance to wear from sliding contact with other metals and abrasive materials.
AISI D3 alloy steel is heat treatable and will offer a hardness in the range 58-64 HRC. After heat treatment D3 SKD1 1.2080 Cr12 tool steel is hard, durable and dense, and is immune from sinking in use. It offers a measure of corrosion resistance when polished. In general, the applications of AISI D3 tool steel resemble those of D2 tool steel but it should be remembered that alloy tool steel D3 has better wear resistance of the two steels and is preferred for such items as shear blades. Owing to its higher wear resistance, AISI / ASTM D3 cold work steel is slightly more difficult to grind than D2 steels.
