Key Material Advantages of Our Forged Gear Shafts:
Exceptional Strength: Engineered to endure high torque and heavy operational loads without bending or failure.
Excellent Machinability: Designed for ease of processing, enabling precise machining and streamlined manufacturing efficiency.
Low Notch Sensitivity: Reduced vulnerability to stress concentrations helps prevent early fatigue or cracking in high-stress zones.
Optimized for Heat Treatment: Capable of achieving superior mechanical properties through various heat treatment processes, ensuring wear and fatigue resistance.
Superior Wear Resistance: Built to deliver long-term performance and minimal wear, even in harsh and continuous-duty applications.
The steel forgings production flow:
Raw material steel ingot into warehouse(test the chemical composition) → Cutting→ Heating(Furnace temperature test) → Heat treatment after forging(Furnace temperature test) Discharge the furnace(blank inspection)→ Machining→ Inspection(UT,MT,Visal dimension, hardness)→ QT→ Inspection(UT, mechanical properties, hardness, grain size)→ Inspection (dimension)→ Packing and Marking(steel stamp, mark)→ Storage Shipment.
