Material Options:
42CrMo – A high-strength alloy steel with excellent toughness and hardenability, widely used for heavy-duty drive shafts.
42CrNiMo – A nickel-molybdenum alloy steel offering superior impact resistance and stability in harsh, low-temperature environments.
18CrNiMo – A carburizing alloy steel combining high surface wear resistance with strong core toughness, ideal for long-life gear shafts.
Key Features:
Weight range: 100–1000KG
Available in various shapes: stepped shafts, spline shafts, solid or hollow structures
Forged and heat-treated for enhanced mechanical properties
CNC pre-machining or rough machining available upon request
100% Ultrasonic testing and Magnetic Particle Inspection
Applications:
Main shafts and input/output shafts in wind turbine gearboxes
High-torque drive components in renewable energy systems
Custom transmission shafts for planetary and parallel gear reducers
Offshore and onshore wind power equipment
Manufacturing Process:
The shafts are produced using open die forging or precision closed die forging, followed by appropriate heat treatment such as quenching & tempering or carburizing. Each part is processed to achieve optimized grain flow and superior fatigue resistance. All products are strictly inspected and can be delivered with pre-machined surfaces to facilitate your final assembly or finish machining.

The steel forgings production flow:
Raw material steel ingot into warehouse(test the chemical composition) → Cutting→ Heating(Furnace temperature test) → Heat treatment after forging(Furnace temperature test) Discharge the furnace(blank inspection)→ Machining→ Inspection(UT,MT,Visal dimension, hardness)→ QT→ Inspection(UT, mechanical properties, hardness, grain size)→ Finish machining→ Inspection (dimension)→ Packing and Marking(steel stamp, mark)→ Storage Shipment.
