Product introduction

EN 34CrNiMo6 Steel is an important alloy engineering steel grade as per BS EN 10083-3:2006. 34CrNim06 steel has high strength, high toughness and good hardenability. EN / DIN 34CrNiMo6 alloy steel has the stability of resistance to overheating, but the white sensitivity of 34CrNiM06 is high. It also has the temper brittleness, so the weldability of 34CrNiMo6 material is poor. The steel 34CrNiMo6 needs the high temperature preheating before welding in order to eliminate the stress after welding processing.

Hardness: 28-32HRC (Q+T condition)
200+ tons daily stock of 34CrNiMo6 steel round bar.
Hot rolled / QT condition available.

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.
