42CrMo Custom Forged Steel Shaft Drive Shaft For Wind Turbines Industrial Gearboxes

Custom 42CrMo Forged Gear Shaft for Wind Turbine and Industrial Gearbox Applications | Open Die Forging. 

This gear shaft is precision forged from high-strength 42CrMo alloy steel, offering excellent toughness, wear resistance, and fatigue strength. It is specially designed for use in wind turbine drivetrains and industrial gearbox systems, where stable torque transmission and long-term reliability are critical.

Through controlled forging and heat treatment, the shaft achieves refined grain structure and optimal mechanical properties. Each piece is custom-produced based on customer drawings, ensuring exact dimensional and performance requirements are met.

Key Features:

• Material: 42CrMo alloy steel

• Process: Forging + Heat Treatment + Rough Machining

• Application: Wind energy gearboxes, industrial drive systems

• Condition: As forged, rough machined, or fully machined

Advantages:

• High torsional and tensile strength

• Excellent fatigue and impact resistance

• Reliable under high-load and cyclic operation

• OEM/ODM custom production available

The steel forgings production flow:

Raw material scrutiny → Unloading of materials → Screening inspection → Preheating treatment → Forging fabrication → Heat treatment application → Quality verification → Rough machining work → Non-destructive examination → Final quality check → Packaging completion → Goods delivery

We have our Own Inspection Lab:  

These are the main inspection equipments:  

We operate a fully equipped in-house laboratory dedicated to mechanical, chemical, and metallurgical testing. This allows us to perform real-time quality checks throughout the entire production process—from raw material selection to final inspection.

Our laboratory testing equipment includes:

Spectral Component Analyzer – for chemical composition analysis

Hydraulic Universal Testing Machine – for tensile and yield strength testing

Impact Strength Testing Machine with Cryogenic Tank – for room temperature and low-temperature impact testing

Brinell & Rockwell Hardness Testers – to assess surface and core hardness

Ultrasonic Flaw Detector – for internal defect detection (UT)

Metallurgical Microscope – for grain structure and heat treatment evaluation

Program-Controlled Box Furnace – for heat treatment simulations and metallurgical testing
