Heat treatment
Isothermal annealing:
- Heat to 880°C, hold at temperature for 1/2 h to 1 h;
- Furnace cooling to 780°Cand hold at temperature for at least 5 hours;
- Cool by 10°C/h to 750°C;
- Cooling in air.
Maximum hardness: 230 HB
Stress relieving:
To be carried out after maching and before the final heat treatment.
- Heat to 650÷700°C, hold for 4÷6 hours;
- Furnace cooling to 300÷350°C;
- Cooling in air.
Hardening:
- Initial preheating to 350÷450°C;
- Second preheating to 750÷850°C;
- Heat to hardening temperature in the range 1000÷1050°Cand hold at temperature;
- Cooling in air.
Quenched hardness: 52÷56 HRC
Tempering:
In the range 550÷630°Cfor at least 3 hours according to hardness requirements and conditions of use.
Tempering must be repeated a second time at a temperature to or 20°Clower than the previous.
Before tempering, preheat the parts to 200÷300°C.
