Product introduction & application
Among the five heavy rail specifications, the 60kg/m specification is the most widely used. Using U71mnG material, LF+VD furnace refining + vacuum degassing technology is adopted to improve the fatigue resistance of subway tunnels, which makes the fatigue crack initiation time extended by 3 times, and at the same time extends the maintenance-free period of subway tunnels to up to 10 years, which greatly saves costs.
Actual application in Beijing Metro Line 17 and Chengdu Metro Line 8.
