Wagon F-Type Coupler Alloy Steel Casting

The wagon F-Type coupler is the core automatic coupling component for heavy-haul freight wagons, usually mounted on the underframe end with draft gear for wagon connection. It is mainly made of AAR Grade E cast steel with quenched-tempered treatment, featuring high strength, minimal coupling clearance and reliable anti-disengagement performance. It withstands huge longitudinal traction, braking forces and coupling impact loads in heavy-haul operations, and its performance directly affects coupling reliability, force transmission efficiency and operational safety of heavy-haul freight trains.
