The spring pin is a cylindrical pin shaft component that has undergone high-strength quenching and tempering treatment. It is typically processed from 45# high-quality carbon steel or alloy structural steel. Some products undergo surface carburizing, quenching, or galvanizing for rust prevention. It combines high strength, high wear resistance, and corrosion resistance. Its core function is to achieve articulation and force transmission between the steel plate spring and the frame, axle, and lifting lugs.
