Rail Transit Industry Solutions

In the rail transit industry, disc springs, as key elastic components, are widely used in braking systems. During their service, disc springs often encounter harsh and complex environments, leading to stress relaxation, high-temperature creep, and corrosion. To enhance performance and ensure long-term stable operation of the equipment, it is necessary to optimize material selection, heat treatment processes, and design.

The heat treatment process and surface treatment process of the material are optimized by the third group. After 180 hours of 5%NaCl neutral salt spray test, no corrosion phenomenon occurs to the disc spring, and the fatigue life can reach more than 1 million times.
