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.
