Material Overview

34CrNiMo6 / 1.6582 Steel is a heat-treatable, low alloy steel used for a wide range of engineering parts. It can be heat treated to produce a typical tensile strength of 1000-1200 N/mm², combined with good ductility and resistance to shock. The material offers excellent hardenability, enabling it to be used for medium tensile strengths in fairly large sections, and attain good wear resistance and impact properties at low temperatures.

Heat Treatment Process

Quenched and Tempered (Q+T) Process

Heat 34CrNiMo6 round steel slowly to 850°C
Soak at hardening temperature and quench in oil
Temper as soon as steel reaches room temperature
Heat uniformly to suitable temperature
Withdraw from furnace and cool in air
Usual tempering temperature is 600°C (depending on requirements)

Additional Processing Information

Forging: Hot forming temperature: 1100-900°C
Machinability: Best performed in annealed or normalized and tempered condition. Can be machined by all conventional methods.
Welding: Can be fusion or resistance welded. Preheat and post-heat weld procedures should be followed.

Applications

EN DIN 34CrNiMo6 steel is used to manufacture tools requiring good plasticity and high strength. It is typically selected for large-size, critical components including:

Heavy machinery axles
Turbine shaft blades
High-load transmission parts
Fasteners and crank shafts
Gears and heavily loaded motor construction parts
