U75V 75KG GB heavy rail: the mainstay of railway transportation

In the railway track system, heavy rail plays a key role, and U75V 75KG GB heavy rail is the best among them.

U75V is an alloy steel grade corresponding to the GB/T 2585-2021 railway hot-rolled rail standard. Its chemical element composition has a specific ratio: carbon (C) content is 0.71-0.80%, silicon (Si) is 0.50-0.80%, manganese (Mn) is 0.75-1.05%, phosphorus (P) ≤0.025%, sulfur (S) ≤0.025%, vanadium (V) 0.04-0.12%, etc. Such chemical composition gives U75V 75KG GB heavy rail a series of excellent properties.​

In terms of strength, it has high strength and hardness, can withstand large loads, provides reliable support for railway transportation, and effectively extends its service life. In terms of fatigue resistance, the heavy rail performs well, can prevent the inner side of the rail head from peeling off and the rail from breaking horizontally, and ensure driving safety. It has strong resistance to uneven wear, and the hardness is uniform over the entire length of the rail, which can avoid uneven wear such as corrugations and waves. Good welding performance makes it easy to lay seamless lines and improve the smoothness of the track. At the same time, it also has good turnout machine processing performance, which helps to obtain high-quality turnouts. ​

In actual applications, U75V 75KG GB heavy rails are often used in important railway projects such as high-speed and heavy-load railways. Since the relevant production lines were renovated in 2008, they have been widely used in many key projects such as Ningqi Passenger Dedicated Line, Xiamen-Shenzhen Passenger Dedicated Line, and Hanyi Railway, playing an important role in my country's railway construction. For example, under high-speed trains, the U75V 75KG GB heavy rail ensures the smooth operation of the train, reduces the workload of track maintenance, and improves the comfort of passengers. ​

In short, the U75V 75KG GB heavy rail has become an indispensable key component in the railway transportation system with its excellent performance, driving the continuous development of the railway industry.
