Quenched and Tempered (Q+T) of 34CrNiMo6 Steel
- Heat 34CrNiMo6 round steel slowly to the temperature of 850°C;
- Soak at this hardening temperature quench in oil;
- Temper as soon as 34CrNiMo6 steels reach room temperature.
- Heat uniformly to the suitable temperature;
- Withdraw from the furnace and cool in the air.
- The usual tempering temperature is 600°C which depending on the actual requirements.
