K6 bogie spring is the key part of bogie, each vehicle consists of 24 outer round springs 1, 4 outer round springs 2, 28 inter round springs, 8 shock absorber outer round springs and inter round springs, the fatigue life reaches to 3 million times and above. K2 bogie spring, the standard used Q/QC35-095-2000, intermediate frequency faradism heating device to achieve a rapid heating, effectively reduced the spring surface oxidation and decarburization.

Fatigue life is up to 2.6 million tim
