Railway transportation occupies a large part of transportation. At the same time, we usually contact more, mostly train passenger vehicles, but a lot of cargo transportation is also completed by railway transportation system. In railway transportation, the quality of railway freight cars must have certain qualities. For example, railway weathering steel and Q450NQR1 series weathering steel are steel materials used in railway vehicles and have good corrosion resistance.
Weathering steel for railway vehicles, adding a small amount of alloying elements such as Cu, P, Cr, Ni, etc. to the steel to form a dense layer between the stainless layer and the substrate to prevent oxygen and water in the atmosphere from flowing to the steel substrate Penetration slows down the development of rust to steel materials, thereby greatly improving the atmospheric corrosion resistance of steel materials. Q450NQR1 has been widely used in 70t and 80t truck manufacturing.
Railway weathering steel, as its name implies, is mainly a weathering steel used in the manufacture of railway freight cars. Of course, it also has its own models and characteristics. In practical applications, choose appropriate specifications of railway weathering steel products according to the needs. Railway weathering steel plate and sheets are mainly used in railway freight car manufacturing.
