Factors affecting wear resistance of rail shoulder

The material selection of the rail shoulder is a key factor affecting its wear resistance. High-quality materials usually have higher hardness and wear resistance, which can maintain the stability of their shape and size during long-term use.

The surface treatment of the rail shoulder is also an important means to improve its wear resistance. For example, the surface of the rail shoulder is treated by sandblasting, shot blasting and other processes, which can increase the roughness of its surface, thereby increasing the friction between it and the elastic fastener to prevent loosening and falling off.

The use environment of the rail shoulder will also have an impact on its wear resistance. For example, in harsh climatic conditions (such as high temperature, low temperature, humidity, etc.), the wear rate of the rail shoulder may be accelerated.
