42CrMo, 42CrNiMo, 18CrNiMo100-1000KGS Precision Forged Steel shaft for Wind Power Turbines. We manufacture precision forged steel shafts using high-performance alloy steels such as 42CrMo, 42CrNiMo, and 18CrNiMo, specifically developed for wind turbine drivetrain systems. With a weight range from 100KG to 1000KG, these shafts are engineered to deliver outstanding strength, fatigue resistance, and dimensional accuracy under continuous high-load operation.
Material Grades:
-
42CrMo – A versatile alloy steel offering excellent toughness, wear resistance, and hardenability, ideal for medium to heavy-duty shafts.
-
42CrNiMo – A nickel-molybdenum alloy steel with superior fatigue and impact resistance, especially suitable for cold climates and dynamic loads.
-
18CrNiMo – A premium carburizing steel known for deep hardenability and superior surface hardness after heat treatment, perfect for long-life drive components.
Key Features:
-
Weight range: 100–1000 KGS
-
Custom shapes: straight shaft, stepped shaft, spline shaft, hollow or solid
-
Close grain structure and directional fiber flow for enhanced fatigue resistance
-
Heat treated for improved performance
-
Precision pre-machined or rough-machined surfaces available
-
Full quality inspection: ultrasonic testing (UT), magnetic particle inspection (MPI), and dimensional checks
Applications:
-
Wind turbine main shafts and gear drive shafts
-
Gearbox input and output shafts
-
Coupling and transmission drive assemblies
-
High-load rotating equipment in renewable energy systems
Production Process:
High-quality alloy steel is forged using open-die or closed-die processes, followed by heat treatment tailored to the final application. Precision forging and controlled cooling ensure optimal grain flow and metallurgical properties. Each shaft is inspected and optionally delivered with CNC pre-machining for seamless integration into wind turbine gear systems.

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.
