34CrNiMo6 hot rolled steel round bars

34CrNiMo6 is a quenching and tempering steel with high strength, high toughness and good hardenability. Used for large axles, machine components, tools and high strength fasteners. The steel can be induction hardened and it is weldable under certain conditions. Through hardenability to appr. 100 mm diameter bar with oil quenching.
34CrNiMo6 hot rolled steel round bars Application

EN DIN 34CrNiMo6 steel is used to make tools which demands good plasticity and high strength. It is usually selected to make the big size and important parts, such as heavy machinery axle,turbine shaft blade, high load of transmission parts, fasteners, crank shafts, gears, as well as heavily loaded parts for motor construction etc.

Gnee Steel is reliable to supply engineering 34CrNiMo6 steels / 1.6582 engineering alloy steels. Please tell us your detailed requirements and have the best offer soon.

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.

9.Application

EN DIN 34CrNiMo6 steel is used to make tools which demands good plasticity and high strength. It is usually selected to make the big size and important parts, such as heavy machinery axle,turbine shaft blade, high load of transmission parts, fasteners, crank shafts, gears, as well as heavily loaded parts for motor construction etc.
