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
