18CrNiMo7-6 Fatigue Resistant Alloy Steel Forgings For Wind Turbine Shafts

Key Features

• Material Advantage: Made from 18CrNiMo7-6 alloy steel, offering high core strength, superior toughness, and excellent hardenability.

• Fatigue Resistance: Optimized for high-cycle fatigue strength, making it ideal for wind turbine applications with dynamic load demands.

• Directional Grain Flow: Forged to ensure continuous, longitudinal grain flow aligned with shaft stress paths for improved durability.

• Heat Treatment: tempered to achieve uniform mechanical properties and increased resistance to wear and stress.

• Dimensional Precision: Capable of tight tolerances for seamless integration into main shaft assemblies.

• Quality Control: Full range of NDT (UT, MT) and mechanical testing to ensure internal soundness and reliability.

• Customizable: Available with semi-machined or fully-machined finishes, anti-corrosion coatings, and tailored end connections.

Application Scenarios

• Wind Turbine Main Shafts: Designed to endure variable wind loads, torque transfer, and long service cycles.

• Yaw and Pitch Drive Components: Suitable for structural parts under fluctuating torsional stresses.

• Offshore Wind Installations: Proven performance in harsh marine environments requiring high fatigue strength and corrosion tolerance.

• Renewable Energy Equipment: Critical rotating elements in sustainable power generation systems requiring long-term reliability.

The steel forgings production flow:

raw material inspection → unloading → inspection → preheating → forging → heat treatment → inspection → rough machining → non-destructive testing → inspection → packaging → delivery.
