1.2327 tool steel applications
1.2327 steel for Cold Heading Die
Excellent combination of high hardness and toughness enables 1.2327 to endure repeated impact and wear in cold heading of high-strength fasteners.
1.2327 steel for Cold Extrusion Die
High compressive strength and good anti-galling properties ensure reliable performance and extended die life in cold extrusion of complex-shaped components.
1.2327 steel for Precision Shear Blade
Superior wear resistance and edge stability make 1.2327 ideal for precision shear blades cutting thin to medium-gauge sheet metal with minimal burr formation.

mechanical properties & heat treatment of 1.2327 steel
| Heat temperature | Start forging temperature | Finish forging temperature | Cooling method |
| 1100 – 1150 °C | 1100 – 1050 °C | ≥ 850 °C | Pit, sand, or furnace cooling |
Annealing
- Heat slowly and uniformly to 720 – 750°C
- Hold at temperature for 2 – 5 hours, depending on section thickness
- Cool slowly in the furnace at a controlled rate down to approximately 600°C
- Then air cool to room temperature
- Hardness after annealing: max. 230 HB
- Annealing in a protective atmosphere is recommended to reduce decarburization
Hardening
- 1.2327 is a low-alloyed, chromium-molybdenum-vanadium alloyed cold work tool steel. It is a shell hardenable grade with high wear resistance. Hardness after quenching can reach up to 67 HRC. Temper immediately after quenching
- Pre-heat (recommended): Where possible, preheat at 400 – 500°C before austenitizing
- Austenitizing temperature: 800 – 820°C or 830 – 850°C.800–820°C: Lower range for oil quenching.830–850°C: Upper range for water or oil quenching
- Holding time: After temperature equalization, hold for 30 minutes per 25mm of section thickness
- Quenching media:Water (for maximum hardness)Oil (preferred for complex shapes to minimize distortion)
- Hardness after quenching: 64 – 67 HRC
Stress relieving
- Perform after rough machining or heavy stock removal, especially for tools with unbalanced cross-sections, to reduce the risk of distortion during final heat treatment
- Heat carefully to approx. 650°C
- Hold at temperature for 1 – 2 hours (or 2 hours per 25mm of section thickness)
- Air cool after holding
- This operation is performed to reduce distortion during heat treatment
Tempering
- Temper immediately after the workpiece cools to handwarm temperature (approx. 50–70°C). Delayed tempering may cause cracking
- Number of tempers: Minimum 2 times. Double tempering is recommended to improve toughness and ensure complete transformation
- Holding time: Soak for at least 1 hour per 25mm of total thickness (minimum 2 hours per cycle)
- Cooling method: Air cool after each tempering cycle (must cool to room temperature before the next tempering)
- Tempering temperature range: 200 – 600°C
