Heat Treatment Recommendations

For customers performing their own heat treatment of 1.2080 tool steel flat bar, FUSHUN METAL recommends the following parameters:

Stress Relieving

Heat slowly to 650-700°C (1200-1290°F)
Hold for minimum 2 hours per 25mm of thickness
Cool slowly in furnace to below 500°C (930°F), then air cool
Recommended before extensive machining to minimize distortion

Annealing

Heat slowly to 800-850°C (1470-1560°F)
Hold for 1-2 hours per 25mm of thickness
Cool very slowly in furnace at a rate not exceeding 10°C (18°F) per hour to 650°C (1200°F)
Continue cooling in furnace
Resulting hardness: 210-250 HB

Hardening

Preheating: Step 1: 550-600°C (1020-1110°F)
Preheating: Step 2: 800-850°C (1470-1560°F)
Austenitizing: 950-980°C (1740-1795°F)
- Lower temperatures for better toughness, higher temperatures for maximum hardness and wear resistance
Holding time: 15-30 minutes after thorough heating
Quenching options:
- Oil: Preferred method for most applications
- Air: Only for simple shapes and small sections
- Martempering: Recommended for complex shapes to minimize distortion
Achievable hardness after quenching: 62-64 HRC

Tempering

Temper immediately after cooling to room temperature
Double tempering recommended (minimum two tempers)
Tempering temperature selection based on desired final hardness:
- 150-180°C (300-355°F): 60-62 HRC (maximum hardness with minimal toughness)
- 180-250°C (355-480°F): 58-60 HRC (balanced hardness and adequate toughness)
- 250-300°C (480-570°F): 56-58 HRC (increased toughness with good hardness)
- 450-500°C (840-930°F): 52-54 HRC (maximum toughness, but reduced hardness)
Avoid tempering in the range of 250-450°C (480-840°F) if possible due to potential temper brittleness
Hold at temperature for minimum 2 hours per temper
Cool to room temperature between tempering cycles
Cryogenic treatment (optional): -70°C to -196°C (-95°F to -320°F) between quenching and first temper to convert retained austenite and enhance dimensional stability

Surface Treatments (Optional)

Nitriding: Can be performed after final heat treatment to further enhance surface hardness (up to 1200 HV)

Machining Tips

Use rigid setups with minimum overhang to minimize vibration and chatter.
Apply adequate cooling, especially when machining in annealed condition.
For complex geometries, machine in the annealed condition before heat treatment.
Use sharp tools and replace at regular intervals to maintain cutting efficiency.
After EDM processing, remove the affected layer by grinding to prevent micro-cracking.
After heavy machining, consider stress relieving to minimize distortion during final heat treatment.
When grinding hardened material, use gentle cutting conditions and abundant cooling to prevent rehardening of the surface.
The high carbide content in 1.2080 causes increased tool wear; adjust tooling selection and cutting parameters accordingly.
Consider using CBN (cubic boron nitride) grinding wheels for more efficient grinding of hardened material.
Allow extra machining allowance (approximately 0.5mm per side) to compensate for potential distortion during heat treatment.

Welding Recommendations

Welding of 1.2080 is extremely difficult due to its high carbon and alloy content and should generally be avoided. If absolutely necessary:

Preheat: 350-400°C (660-750°F)
Filler Material: Special high-carbon, high-chromium welding electrodes
Process: TIG/GTAW only, with highly skilled operators
Interpass Temperature: Maintain 350-400°C (660-750°F)
Post-weld Heat Treatment: Essential - full annealing followed by complete rehardening and tempering cycle
Limitations: Only consider for minor repairs; structural welds not recommended
Alternative: Consider brazing with high-temperature alloys for joining operations rather than fusion welding
