17NiCrMo6-4 Alloy Steel Forgings Low Speed Shaft And High Speed Shaft Spindle

Customized Alloy Steel Low Speed Shaft And High Speed Shaft Spindle

Customized Alloy Steel Low Speed Shaft And High Speed Shaft Spindle. In the demanding fields of marine and mechanical equipment manufacturing, the quality and performance of materials are of utmost importance.

Our alloy steel forgings, including 17NiCrMo6 - 4, 18CrNiMo7 - 6, and 35CrMo, are precisely engineered to meet the stringent requirements of these industries. These forgings serve as critical components in various assemblies, ensuring reliable operation and long - term durability.

Key Features:

• Materials Available: 42CrMo, 40CrNiMo, 20CrMnMo, 18CrNiMo7-6, and other alloy steels

• Shaft Types:

  • Low-Speed Shaft: Designed for high torque, excellent impact resistance

  • High-Speed Shaft: Precision balanced, suitable for high RPM and thermal stability

• Forging Process: Open die / free forging, with or without pre-machining

• Heat Treatment:Normalizing and tempering

• Machining Service: Rough to finish machining per customer drawings

• Max Weight: 7 tons per piece

Applications:

• Wind turbine gearboxes (main shaft, intermediate shaft)

• Port cranes, rolling mills, and mining drives

• High-speed spindles in industrial reducers and compressors

Advantages:

• High dimensional accuracy and surface finish

• Excellent fatigue, wear, and torsional resistance

• Full traceability with mill certificates and NDT reports

• OEM production with flexible batch sizes

The steel forgings production flow:

raw material inspection → unloading → inspection → preheating → forging → heat treatment → inspection → rough machining → non-destructive testing → inspection → packaging → delivery.
