Track steel has good wear resistance and corrosion resistance. Railway tracks will be subject to friction and wear from trains during use, so track steel must have good wear resistance to extend its service life. Track steel also needs to have good corrosion resistance to cope with various harsh environmental conditions that may be encountered in railway transportation, such as moisture, acid rain, etc.
Track steel has high geometric accuracy and flatness. The geometric accuracy and flatness of railway tracks directly affect the driving stability and comfort of trains. Track steel has high geometric accuracy and flatness, which can ensure that the flatness and geometric accuracy of railway tracks meet standard requirements, thereby improving the driving stability and riding comfort of trains.
Track steel also has high weldability and processability. The laying and maintenance of railway tracks require cutting, welding and processing of track steel. Track steel has high weldability and processability, making the processing and maintenance of track steel more convenient and efficient.

As an important part of railway tracks, track steel plays a vital role in railway transportation. It has the advantages of high strength, wear resistance, corrosion resistance, high geometric accuracy and flatness, and good weldability and processability, making it an ideal material for railway track construction.
The type of rail is expressed in kilograms of rail mass per meter of length. The rails used on my country’s railways include 75kg/m, 60kg/m, 50kg/m, 43kg/m and 38kg/m.
