Product Introduction & Application
Compared with U75V material, U78CrV material has a higher performance. U stands for rail steel, and the numbers and letters represent the percentages of various elements such as carbon, chromium and vanadium, which have excellent strength and durability. 75kg/m is often used in heavy-duty lines in GB standards. It has high fatigue resistance and is very suitable for high-traffic and high-speed lines. The rail has the ability to withstand extreme loads and hard forces. The most famous line in China that uses 75kg/m heavy rails is the "Daqin Line", which has the world's largest annual transportation volume. This shows the load-bearing capacity of the 75kg/m heavy rail specification.
