18CrNiMo7-6 Forged Shaft Blank

The 18CrNiMo7-6 Alloy Steel Forged Shaft Blank for Wind Power Main Shaft Assembly is specifically engineered to meet the demanding mechanical and fatigue requirements of modern wind turbines. Forged from high-grade 18CrNiMo7-6 alloy steel, this shaft blank provides superior core hardness, excellent impact resistance, and outstanding toughness under fluctuating loads.

With its optimized grain flow and uniform metallurgical structure achieved through open-die forging and precision heat treatment, this forged shaft blank is ideal for use as a main shaft component in large-scale wind power systems.


ItemDetails (Wind Turbine Main Shaft – 18CrNiMo7-6)
Available Materials18CrNiMo7-6 (primary), with optional grades including 20CrMnTi, 20CrMnMo, 42CrMo4, 17NiCrMo6-4, 35CrMo, C45, 20CrMo, etc.
Forging EquipmentOpen-die hydraulic hammers (5T / 8T / 12T) – Ideal for long shaft deformation and precise grain alignment
Application FieldDesigned as a main shaft in wind turbine transmission systems, transferring torque under variable loading conditions
Manufacturing ProcessForging → Heat Treatment (Normalizing + Tempering) → Rough Machining – Guarantees internal strength and dimensional consistency
