Product Introduction & Application
According to the current standard GB/T 2585-2017 "Hot-rolled rails for railways", the height of 75kg/m GB heavy rail is 192mm, the bottom width is 150mm, the head width is 75mm, and the waist thickness is 20mm.
Usually, materials such as U71Mn, U75V, and U78CrV are used. U78CrV is often used for extremely overloaded lines. The carbon content of U75V material is 0.71% - 0.80%, the manganese content is 0.75% - 1.05%, and the vanadium content is 0.04% - 0.12%. The tensile strength is not less than 980MPa, the yield strength is not less than 440MPa, and the elongation is not less than 9%.
The strength, hardness, corrosion resistance, and wear resistance of heavy rails are improved by using steelmaking, rolling, heat treatment, surface treatment and other technologies.
It is mainly used in national railway trunk lines, heavy-haul railways, etc. In heavy-haul railways, due to its high strength and good wear resistance, it can meet the requirements of large-volume and high-density train operation.
