mechanical properties & heat treatment of 1.2210 steel
| Heat temperature | Start forging temperature | Finish forging temperature | Cooling method |
| 1050 – 1080 °C | 1050 – 1000 °C | ≥ 850 °C | Pit, sand, or furnace cooling |
Annealing
- Heat slowly to 710 – 850°C (typical: 710–750°C)
- Hold for sufficient time (approx. 2 – 5 hours, depending on section thickness)
- Cool slowly in the furnace at a controlled rate of 10 – 20°C/h down to approximately 600°C
- Then air cool to room temperature
- Hardness after annealing: max. 220 – 223 HB
Hardening
- Preheating (recommended): Preheat slowly to 600 – 650°C to avoid thermal shock
- Austenitizing temperature: 780 – 840°C.Water quenching: typically 780 – 820°C.Oil quenching: typically 800 – 840°C
- Holding time: After temperature equalization, hold for 15 – 30 minutes
- Quenching media:Water (higher cooling rate, for maximum hardness)Oil (preferred for most applications to minimize distortion)For complex shapes, water-oil dual quenching or alkali bath is recommended
- Hardness after quenching: 64 – 66 HRC
Stress relieving
- Perform after rough machining or heavy stock removal to reduce the risk of distortion during final heat treatment
- Heat carefully to approx. 650°C
- Hold at temperature for 1 – 2 hours
- Air cool
- This operation is performed to reduce distortion during heat treatment
Tempering
- Temper immediately after the workpiece cools to hand-warm temperature (approx. 50–70°C). Avoid delaying tempering
- Number of tempers: Minimum 2 times. Double tempering is recommended to ensure complete transformation and property stability
- Holding time: Soak for 1 hour per 20mm of section thickness (minimum 2 hours per cycle)
- Cooling method: Air cool after each tempering cycle
- Tempering temperature range: 100 – 400°C (tempering above 400°C is not typical for this grade, as hardness drops significantly)
