34CrNiMo6 Round Bar Supplier

Looking for 34CrNiMo6, 1.6582 +QT or EN 10269 round bars?

WTE PowerSteel is a European supplier and stockholder of 34CrNiMo6 (1.6582 +QT) chromium-nickel-molybdenum alloy steel for demanding engineering and high-strength applications. We supply certified round bars with full material traceability, EN 10204 3.1 certification and fast worldwide delivery.

34CrNiMo6 is a quenched and tempered alloy steel offering an outstanding combination of high tensile strength, toughness and through hardenability. The chromium, nickel and molybdenum alloying elements provide excellent fatigue resistance and mechanical performance under severe dynamic and static loads, making the material one of the preferred choices for highly stressed engineering components.

The alloy is widely used for manufacturing crankshafts, transmission shafts, gears, turbine components, heavy-duty fasteners and other critical machine parts. Thanks to its excellent mechanical properties after heat treatment, 34CrNiMo6 is extensively used in power generation, heavy engineering, mining, automotive, aerospace and Oil & Gas industries.

Why Choose 34CrNiMo6?

Compared with conventional alloy steels, 34CrNiMo6 (1.6582) provides significantly higher strength, toughness and hardenability while maintaining excellent fatigue resistance.
