42CrMo Alloy Steel Forging Metal Shaft Blank Rough Machined Forge For Metal Wind Power Industry

42CrMo Alloy Steel Metal Forgings Shaft Blank Rough Machined For Wind Power Industry. This forged shaft blank is made from high-strength 42CrMo alloy steel, offering excellent toughness, fatigue resistance, and hardenability. Designed for the demanding requirements of the wind power industry, it serves as a core mechanical component in wind turbine gear transmission systems.

The shaft blank is rough machined to precise dimensional tolerances, ensuring ease of further processing and seamless integration into large-scale industrial assemblies. With our advanced forging technology and strict quality control, each piece guarantees uniform internal structure, high load-bearing capacity, and long service life in harsh operating environments.

These are the main inspection equipments:

Our forged gear shafts provide following material characteristics:

- High Strength: Gear shafts must withstand torque and heavy loads without deformation.

- Good Machinability: Easy manufacturability and precision are essential for efficient production.

- Low Notch Sensitivity Factor: Minimize stress concentration points to prevent premature failure.

- Good Heat Treatment Properties: Ensure durability and resistance to wear and fatigue.

- High Wear Resistance: Gear shafts should have a long service life even under demanding conditions.
