5.Heat Treatment of 34CrNiMo6 Engineering Steel
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.
