会社のニュース What Materials and Processes Ensure the Durability of Railway Axles

The durability of a railway axle depends largely on the materials and manufacturing processes used. Since the axle bears both static and dynamic loads it must have high strength toughness and fatigue resistance. The most common materials are forged alloy steels such as 30CrMo or 40CrNiMoA which offer excellent mechanical properties.

Our factory uses precision forging CNC turning and quenching techniques to achieve optimal structure and dimensional accuracy. Each axle is heat treated to balance hardness and ductility. Ultrasonic inspection and magnetic testing are applied to detect internal defects and ensure product integrity.

We also use advanced surface finishing and coating technologies to prevent corrosion and extend service life. Each production batch follows strict quality standards and traceability systems.

The axle manufacturing process includes forging machining heat treatment and final inspection. Every stage is monitored to guarantee consistent performance.

High quality materials combined with precision engineering ensure that our railway axles can withstand heavy loads long operation hours and harsh environments. This level of quality helps railway operators reduce maintenance costs and improve safety across the entire network.
