The few elements on the rail vehicles such as the bogies have many different variants. These components are mainly composed of welding structures, with different loads but always very high. For example, on the German ICE high speed train, half of all the axle is driven, and the tilt angle of the bogie can be adjusted.

To provide undisputed material selection for these components, we need high precision and high standard customized production, which must have the maximum production efficiency and flexibility. It can provide the first-class service for the rail transportation industry to meet the specific needs of the customers.

On track vehicles, most of today's use is the whole wheel (Dan Tilun). These safety related vehicle elements must be able to withstand huge physical loads and temperature loads. The requirements for materials and manufacturing processes are correspondingly higher.

Forged steel (tensile strength is up to 350HB) must be professionally smelted and forged. Because of its surface quality, it has a direct impact on the driving performance and energy efficiency. Chang Ruilong metal track special steel can easily cope with these challenges, to provide users with a programme of economic material the highest surface precision, safety and flexibility.
