Nitriding:
Reduces the corrosion resistance
Use
Moulds for processing corrosive plastics
Heat treatment
Already pre-hardened; usually no heat treatment required
Soft annealing:
760 to 800 °C, about 4 to 5 hours
Slow controlled cooling inside the furnace of 10 to 20 °C per hour to about 650 °C
Further cooling in air, max. 230 HB
Hardening:
1,030 to 1,050 °C
Maintain curing temperature for 15 to 30 minutes
Quenching in water/oil
Obtainable hardness: 49 HRC
Tempering:
Slow heating to tempering temperature immediately after hardening
Minimum time in furnace: 1 hour per 20 mm part thickness
Technical tip
- Corrosion resistant like 1.2085
- For demanding surfaces
