Cr14 is specially developed grade in recent years. Higher content of Cr 13.5%~15% gives better hardenability of steel and has the effect of secondary hardening, which can improve the hardness and wear resistance of carbon steel without making the steel brittle. Chromium is the main alloying element of stainless acid-resistant steel and heat-resistant steel.

5. 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.
6. 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.
7. Applications of AISI D3 Cold Work Tool Steel
AISI D3 Cold Work Steel has high strength, good hardenability and wear resistance. D3 is suitable for applications such as complex blanking and forming tools for long runs and for hard and abrasive materials.
Typical Applications:
· Highly stressed cutting
· Punching tools for thin sheets,
· Shear blades for cutting
· Profile rolls,
· Drawing and deep drawing tools,
· Stone processing tools,
· Knives for paper and plastics,
· Shear knives for thin sheets.
· Deep drawing,
· Pressure pads
· Highly wear-resistant plastic moulds.
