AISI D6 tool Steel Forged
Pre-heat to 700°C slowly， then rapidly to 900-1050°C start forging. After forging cool slowly to room temperature in furnace.
AISI D6 cold work Steel Annealing
D6 tool steel is supplied in the annealing and machineable. Heat to 800-840°C and slowly cool ing furnace. Get hardness about 225HB.
AISI cold work D6 Steel Stress relieving
If machining have been heavy,remove stresses before hardening by heating up to 650-700°C. then cool slowly.
Quenching of D6 Tool Steel metal material grade
Heat to 750-800 soak enough time until to thoroughly. The re-heat to 950-980°C , hold these temperature ensure heat thoroughly. Cool in air or quench in oil. Vacuum (high speed gas) hardening is perfect.
Tempering of D6 tool steel grade metal material
Heat uniformly to Temper at tempering temperature. Double tempering is perfect.
| Temperature [°C] | 100 | 200 | 300 | 400 | 500 | 600 |
| Hardness [HRC] | 63 | 62 | 60 | 58 | 56 | 48 |
AISI D6 Steel Mechanical Properties
- Poisson’s ratio 0.27-0.30
- Izod impact unnotched 28.0 J
- Elastic modulus 190-210GPa
AISI Cold D6 tool Steel Physical Properties
- Density: 7.85kg/cm3
Thermal Properties of AISI D6 alloy tool steel cold work
- Thermal expansion: 12 x 10-6/ºC, 20-100°C
Heat Treatment AISI Cold work alloy Steel D6 maetrial grade
D6 steel material heat treatment including the heating rate, soaking times, cool, these such as the different shape and size of each D6 steel component. Preheat to 900°C, keep enough time, Re-heat temperature 800-1040°C and again soak for three to four hours. Allow to cool in the furnace to room temperature
Application of AISI D6 cold work tool steel Materials grade
D6 steel application such as complex blanking and forming tools for long runs and for hard and abrasive materials. It is commonly, informs the for other applications to the as brick and tile mould liners, master hobs for cold hobbing plastic moulds, tabletting punches and sleeves for corrosive powders.
