[0002] Sherardizing parts refer to parts that have been treated with the sherardizing process. Sherardizing is a surface treatment technology that immerses the parts in molten zinc liquid to allow zinc atoms to penetrate into the surface layer of the parts, thereby improving their corrosion resistance and wear resistance. Among them, fastener screws, bolts, nuts, clips, washers and other parts are widely used in railway vehicles and track facilities to fix rails and sleepers to ensure the stability and safety of the tracks.
