Heavy-Duty Carbon Steel 45# Coupling Forgings for Mining Conveyors.Heavy-Duty Carbon Steel 45# Coupling Forgings are robust power-transmission components manufactured for high-torque mining conveyor systems. Utilizing open die forging of 45# medium-carbon steel, these forgings deliver exceptional impact resistance and structural integrity in abrasive, high-vibration environments. Engineered to connect drive shafts and pulleys under continuous heavy loads.
Superior Shock Load Resistance
Optimized grain flow withstands conveyor start-up torque spikes.
Enhanced Wear Resistance
Forged surface hardness tolerates abrasive coal/ore dust.
Minimal Defect Probability
≥3:1 forging ratio eliminates internal voids and inclusions.
High Torque Capacity
Shear strength prevents deformation under overloads.
Corrosion Mitigation
Shot-blasted surface preparation enables effective protective coating.
| Conveyor Zone | Component Function |
