Heavy Steel Forgings For Wind Turbine Main Shaft Applications

Heavy Steel Forgings for Wind Turbine Main Shaft Applications

Our heavy steel forgings for wind turbine main shafts are engineered for maximum reliability and performance under continuous load conditions. Produced from premium alloy steels such as 42CrMo4 and 34CrNiMo6, each shaft forging undergoes precise temperature control, optimized deformation, and full ultrasonic testing to guarantee internal soundness and long service life.

Product Features

• High tensile and yield strength ensuring superior load-bearing capacity

• Excellent impact toughness and fatigue resistance under dynamic stresses

• Uniform grain structure achieved through controlled forging and heat treatment

• Full ultrasonic inspection to ensure defect-free internal quality

• Available in customized dimensions and heat treatment conditions

Applications

• Wind turbine main shafts for onshore and offshore installations

• Power transmission shafts in hydroelectric and marine equipment

• Heavy-duty gear components in industrial and metallurgical machinery

• Structural parts requiring high strength and long-term operational reliability

Process Flow

Raw material confirmation and chemical composition verification → Cutting of ingots or billets to specified sizes → Controlled preheating in a temperature-monitored furnace → Precision open-die forging of the main shaft blank → Immediate post-forging heat treatment to refine grain structure → Cooling and visual inspection of surface and shape → Rough machining for dimensional stability → Intermediate quality inspection including UT, MT, and hardness testing → Quenching and tempering (Q&T) to achieve the desired mechanical properties → Final quality verification with ultrasonic testing, tensile and impact tests, hardness, and metallographic examination → Finish machining to precise tolerances → Final dimensional and surface inspection → Product marking, anti-corrosion coating, and packing → Storage and preparation for shipment.
