1. Annealing
Slowly heat the steel to 850-900°C and hold for 2-4 hours. Then, allow the furnace to cool to below 600°C, followed by air cooling.
This process achieves an annealed hardness of ≤ 255 HB, ensuring good machinability before hardening.
2. Hardening (Quenching)
Preheat in stages:
First to 450-500°C
Then to 850-900°C
Finally, heat to the austenitizing temperature of 1140-1160°C and hold for a suitable time based on section size.
Quench rapidly in oil, salt bath, or vacuum gas quenching to achieve optimal hardness and a fine, uniform microstructure.
3. Tempering
Temper immediately after quenching to relieve internal stresses and enhance toughness.
The recommended tempering temperature range is 540-600°C.
Double or triple tempering is advised for optimal performance.
After tempering, the hardness typically reaches 64-66 HRC, depending on specific parameters and section size.
