mechanical properties & heat treatment of 1.2360 steel
| Heat temperature | Start forging temperature | Finish forging temperature | Cooling method |
| 1120 – 1150 °C | 1080 – 1120 °C | ≥ 900 °C | Pit or sand cooling (slow cooling required) |
Annealing
- Heat to 830 – 860°C (slow heating).
- Hold for sufficient time to ensure uniform temperature throughout the section (typically 2–4 hours depending on thickness).
- Cool slowly in the furnace at a controlled rate (max. 10–20°C/h) down to approximately 500°C
- Then air cool to room temperature
- Hardness after annealing: max. 240 HB
Hardening
- Preheating (recommended): First stage at 600 – 650°C, second stage at 830 – 850°C
- Austenitizing temperature: 1030 – 1070°C (or 1080–1120°C for oil quenching specifically)
- Holding time: After temperature equalization, hold for 15–30 minutes
- Quenching media: Oil, air, or salt bath (at approx. 500–550°C)
- Hardness after quenching: 60 – 61 HRC
Stress relieving
- Perform after rough machining or heavy stock removal
- Heat carefully to approximately 650°C
- Hold for 1–2 hours (or 2 hours per 25mm section thickness)
- Furnace cool slowly to approximately 500°C, then air cool
Tempering
- Number of tempers: Minimum 2 times. Three tempers are recommended for complex shapes or critical applications to ensure complete transformation and optimal property balance
- Method: Heat uniformly to the required tempering temperature; hold for 1 hour per 20mm of section thickness (minimum 2 hours); then air cool
- Conduct tempering immediately after the workpiece cools to hand-warm temperature (approx. 50–70°C)
- Tempering temperature vs. hardness reference: Tempering Temperature Hardness (HRC) 100 °C 61 200 °C 60 300 °C 58 400 °C 58 500 °C 60 550 °C 57 600 °C 53
