AISI D6 Cold Worked Mold Steel
AISI D6 is a high-carbon, high-chromium tool steel that is commonly used in the manufacturing of cutting and shaping tools, such as knives, punches, and dies. It offers excellent wear resistance, good toughness, and high hardness, making it suitable for applications where high levels of wear and abrasion are expected. DIN 1.2436 is often used in the production of cold work tools, such as cold heading dies, blanking dies, and cutting tools for sheet metal. It can also be used in applications where high precision and dimensional stability are required.

AISI D6 Cold Worked Tool Steel 
| 1: AISI D6 steel introduction AISI D6 tool steel is a high-carbon, 12% chromium alloy cold work tool steel with tungsten. AISI D6 steel is an air hardening alloy tool steel with excellent resistance to wear and abrasion. As a high carbon high chromium tool steel D6 has better through hardening properties than D3 steel and dimensional stability combined with high resistance to tempering 2: AISI D6 Steel equivalent

6: Heat Treatment
Forging
Heat slowly to 700°C and then more rapidly to 900-1050°C. After forging cool slowly, preferably in a furnace.
Annealing
As this grade is supplied in the annealed and machineable condition re-annealing will only be necessary if it has been forged or hardened. Anneal the steel at 800-840℃ and slow furnace cool. Hardness after annealing will be approximately 225HB.
Stress Relieving
When machining operations have been heavy or if the tool has an unbalanced section, remove stresses before hardening by heating up to 650-700℃, equalise, cool slowly.
Hardening
Pre heat slowly to 750-800℃ and soak thoroughly. Continue heating up to the final hardening temperature of 950-980℃, allow the component to be heated through. Cool in air or quench in oil. X210CrW12 is suitable for vacuum (high speed gas) hardening.
Tempering
Heat the steel uniformly and thoroughly at the selected tempering temperature and hold for at least one hour per 25mm of total thickness. Double tempering of X210CrW12 should be carried out with intermediate cooling to room temperature.
| Temperature [℃] | 100 | 200 | 300 | 400 | 500 | 600 |
| Hardness [HRc] | 63 | 62 | 60 | 58 | 56 | 48 |
Heat Treatment
Heat treatment temperatures, rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each component. Other considerations during the heat treatment process include the type of furnace, the quenching medium and work piece transfer facilities. Please consult a heat treatment specialist for full guidance on heat treatment.
7: Delivery condition
