Railway axles

The railway axle is a key component of the train wheel set. It connects the wheels and axles of the train, supports the weight of the vehicle, and transmits traction and braking force. Railway axles are usually made of special alloy steel that has been heat treated, such as 40 steel, 50 steel or 60 steel. These materials have high strength, wear resistance and corrosion resistance and can meet the operational needs of trains and high-speed rail. In addition to alloy steel and stainless steel, some new materials are also used to make shafts for trains and high-speed rail. For example, carbon fiber composite materials have the advantages of lightweight, high strength and corrosion resistance, which can significantly reduce the weight of axles and improve the performance and efficiency of trains. In addition, some new alloy materials also have excellent mechanical properties and corrosion resistance, which can meet the operating requirements of trains and high-speed rail.
