HEAT TREATMENT:
already pre-toughened; usually no heat treatment required
Soft annealing:
760 to 800 °C for about 4 to 5 hours; slow controlled cooling of 10 to 20 °C per hour to about 650 °C; further cooling in air, max. 230 HB
Hardening:
1030 to 1050 °C 15 to 30 minutes keeping curing temperature 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
