42CrMo 20CrNi2Mo Custom Forged Steel Flanges High-Strength Design
Applicable To Energy, Chemical Industry
1. Wind Turbine Main Shafts – 42CrMo Forgings
We manufacture wind turbine main shafts using premium 42CrMo and
alloy steels through open die forging. Designed to withstand high
torque, axial loads, and long-term fatigue, our forged shafts
deliver exceptional mechanical strength and reliability in harsh
wind farm environments.
All forgings are available in custom lengths and diameters, support
small-batch orders, and include full material certificates (EN10204
3.1/3.2). With in-house rough machining and strict quality control,
we ensure each shaft meets your exact technical standards. Regular
exports to Europe and Latin America available.
The 42CrMo ,20CrNi2Mo(raw materials can be customized as required)
high-speed flange is specifically designed for use in
high-performance mechanical systems such as gearboxes, turbines,
and rotating equipment. Manufactured through precision open-die or
closed-die forging processes, this flange ensures excellent fatigue
resistance, mechanical strength, and dimensional stability under
high-speed operation.
