High-Performance Forged Gears for Wind Energy Applications
Our forged gears are widely used in wind power gearbox systems, especially in high-load planetary and helical gear stages. 42CrMo4 and 40Cr alloy steels are selected for their superior mechanical performance after quenching and tempering treatment, offering:
High tensile and yield strength
Excellent impact toughness
Superior wear and fatigue resistance
Enhanced hardenability and stability
These properties make our gears particularly suitable for offshore and onshore wind turbines, where components must withstand fluctuating loads, temperature variations, and long-term vibration.
