High-Quality Forged Gear Blanks – 20CrMnTi, 18CrNiMo7-6, 42CrMo Alloy Steel

We specialize in manufacturing premium forged gear blanks using top-grade materials such as 20CrMnTi, 18CrNiMo7-6, and 42CrMo. These alloy steels offer excellent mechanical strength, wear resistance, and hardenability, making them ideal for heavy-duty applications in wind turbines, industrial gearboxes, construction machinery, and marine equipment.

All forgings are produced through precision-controlled processes to ensure optimal grain flow, uniform hardness, and dimensional accuracy. Available in customized sizes and heat treatment conditions, our metal forgings meet international standards and are inspected with ultrasonic testing to guarantee quality. Partner with us for reliable forged components that power performance and durability.

Product Features

• High Surface Hardness
  Through precision carburizing and quenching, the gear achieves a surface hardness of HRC58–62, ensuring excellent wear resistance under continuous high-load operation.

• Superior Core Toughness
  20CrMnTi alloy steel provides a strong, ductile core, enhancing shock absorption and crack resistance during frequent acceleration and braking cycles.

• Optimized Tooth Geometry
  Advanced hobbing and finishing techniques ensure low noise, high contact precision, and smooth torque transmission.

• Long Service Life
  Engineered to resist surface pitting, scuffing, and tooth root fatigue, significantly extending maintenance intervals and lowering life-cycle costs.

• Consistent Dimensional Stability
  Thermal and mechanical treatment ensures tight tolerances are maintained, critical for gearbox reliability at high speeds.

Application Scenarios

• Railway Traction Gearboxes
  Used in drive systems of electric and diesel locomotives, high-speed trains, metro cars, and light rail vehicles.

• High-Load Transmission Units
  Suitable for main traction gears, intermediate transmission stages, and reduction gears in railway powertrains.

• Urban Mass Transit & Intercity Rail
  Reliable under frequent start-stop conditions and high cycling demand typical in city and regional transport systems.

• Heavy-Duty Mobility Systems
  Ideal for axle-mounted gearboxes and gear-coupled wheel drives requiring durability, precision, and low maintenance.
