4.Heat treatment
Annealing:
-Heat to 750~800℃, with hold at minimum rate for 3 hours.
-Furnace cooling.
Stress relieving:
To be carried out after machining and before the final heat treatment.
Heating to 600~650°C for 2 hours.
Hardening:
Preheating to 600~700℃;
- Austenitizing at 990~1040℃
- Oil or thermal bath cooling at 500~550℃, then oil cooling according to the steel shape and size.
Quenched hardness: HRC 52~56
Tempering:
To be carried out after hardening according to the required hardness; at 170-270℃ in order to match hardness and resistance to corrosion; permanence for at least 2 hours;
Tempering must be repeated at least twice at a temperature 30 ℃ lower than the previous. Cooling in air.
