Product Introduction

The dimensional accuracy requirements of heavy rails are very high to ensure the flatness of the track and the accuracy of the track gauge, thereby ensuring the smoothness and safety of train operation.

High precision GB U71Mn and U75V heavy rails are two common heavy rails for railways. U71Mn has excellent mechanical properties, and its tensile strength, yield strength and other indicators can meet the technical standards of high-speed railways and other high-speed railways. It has good fatigue resistance and impact resistance, and can withstand the load generated by long-term operation of trains. U75V has excellent mechanical properties and can meet the use requirements of high-speed and heavy-load railways. It has high hardness and wear resistance, and has excellent performance in fatigue resistance, wear resistance and deformation resistance, which can effectively extend the service life of rails and reduce maintenance workload.
