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.
APPLICATIONS
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.

PROCESSING
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.
