U71Mn tensile strength is not less than 880MPa, yield strength is not less than 580MPa, and elongation is not less than 10%. U75V tensile strength is not less than 980MPa, yield strength is not less than 680MPa, and elongation is not less than 8%.
U71Mn is widely used in ordinary railway trunk lines, branch lines, and factory and mine dedicated lines. It can meet the needs of railway transportation with medium volume and speed requirements, and has good comprehensive performance and economy. U75V is often used in heavy-duty railways and high-speed railways, which have high requirements for rail performance. Its high strength, high wear resistance and good fatigue resistance can better withstand the load of heavy-duty trains and high-speed trains, and extend the service life of rails.
