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.

6.Forging of DIN 34CrNiMo6 / 1.6582 Steel

Hot forming temperature: 1100-900oC.

7.Machinability of Steel 34CrNiMo6

Machining is best done with this 1.6582 alloy steel in the annealed or normalized and tempered condition. It can be machined by all conventional methods.

8.Welding

The alloy materials can be fusion or resistance welded. Preheat and post heat weld procedures should be followed when welding this alloy by established methods.
