Quenched And Tempered Forged Flanges For Large Gear Assemblies

Quenched and Tempered Forged Flanges for Large Gear Assemblies

Quenched and tempered forged flanges are engineered for use in heavy-duty gear assemblies, where high strength and dimensional accuracy are critical. Manufactured from premium alloy or carbon steels, these flanges undergo controlled forging and heat treatment to achieve excellent toughness, wear resistance, and fatigue strength. The quenching and tempering process ensures a refined microstructure, delivering long service life even under continuous torque and vibration loads.

Product Features:

• Manufactured from high-quality alloy and carbon steels

• Quenched and tempered for enhanced toughness and fatigue resistance

• Excellent wear resistance and dimensional stability

• Reliable performance under continuous torque and vibration

• Long service life in heavy-duty applications

Applications:

• Large gear assemblies in wind power equipment

• Metallurgical and mining machinery

• Port cranes and lifting systems

• Heavy-duty transmission and drive systems

Process Flow:
Material verification → unloading and receiving → quality check → controlled preheating → forging operation → heat treatment → intermediate inspection → rough machining → NDT testing → final inspection → protective packing → shipment.
