Thread Rail Fasteners Screw Spike Durable Corrosion Resistant

The wear resistance of railway spikes is one of the important indicators to measure their quality. When the train is running at a very high speed, the spikes can firmly fix the rails to ensure the safety and comfort of the train operation. When the train wheels roll on the rails, they will produce friction with the rails, and this friction will be transmitted to the spikes through the rails.

If the wear resistance of the spikes is insufficient, the surface of the spikes will gradually wear under the action of long-term friction, resulting in an increase in the matching gap between the spikes and the rails and sleepers, which will affect the fastening effect of the spikes. In order to improve the wear resistance of the spikes, the surface of the spikes will be specially treated during the manufacturing process, such as quenching, carburizing, etc., to increase the surface hardness.
