Precision Steel Gears Alloy Powdered Steel For Forging For Wind Turbine Gearbox
Our Precision Alloy Steel Forged Gear for Wind Turbine Gearbox Application is engineered to deliver exceptional performance and durability in harsh wind power environments. Manufactured using high-grade alloy steels such as 18CrNiMo7-6 and 42CrMo4, this forged gear offers superior hardness, wear resistance, and load-bearing capacity—making it ideal for main drive, yaw, and pitch gearboxes in both onshore and offshore wind turbines.
With advanced forging and heat treatment processes, each gear maintains optimal microstructure integrity and dimensional accuracy, ensuring long-term reliability and minimal maintenance. Ultrasonic testing (UT), magnetic particle inspection (MPI), and other non-destructive tests are performed to meet international quality standards.
