Material Overview

34CrNiMo6 / 1.6582 Steel is a heat-treatable, low alloy engineering steel designed for a wide range of demanding applications. This material can be heat treated to achieve tensile strengths of 1000-1200 N/mm² while maintaining excellent ductility and shock resistance. It offers superior hardenability, allowing for medium tensile strengths in large sections, along with excellent wear resistance and impact properties at low temperatures. The steel is readily machinable and can be supplied in annealed condition for enhanced machinability or in hardened and tempered condition with hardness of 28-34HRC.

Processing Characteristics

Heat Treatment (Quenched and Tempered)

Slowly heat to 850°C hardening temperature
Soak at temperature and quench in oil
Temper immediately after reaching room temperature
Heat uniformly to appropriate tempering temperature (typically 600°C)
Withdraw from furnace and air cool

Forging

Hot forming temperature range: 1100-900°C

Machinability

Best machined in annealed or normalized and tempered condition. Compatible with all conventional machining methods.

Welding

Suitable for fusion or resistance welding. Requires preheat and post-heat procedures following established welding methods.

Applications

EN DIN 34CrNiMo6 steel is ideal for tools requiring high strength and good plasticity. Commonly used for large, critical components including heavy machinery axles, turbine shafts, high-load transmission parts, fasteners, crankshafts, gears, and heavily loaded motor construction components.
