Transportation equipment materials
350km/h high-speed rail is widely used in key domestic routes, making positive contributions to the construction of the national "Belt and Road" and the implementation of the strategy of high-speed rail "going out". Weathering steel for high-speed railway carriages has high corrosion resistance, and its good molding performance and low-temperature toughness can ensure the stable operation of vehicles in harsh environments.
