According to the latest “2025 Railway Development Report” released by China National Railway Group, by the end of 2025, the operating mileage of high-speed rail in China has exceeded 50000 kilometers, accounting for more than 70% of the total global high-speed rail mileage. Behind this figure is the annual investment of over 400 billion yuan in high-speed rail construction and the continuously growing market demand. The vast high-speed rail network has put forward higher requirements for fastener products. In the field of rail transit, fasteners not only need to withstand the huge vibrations and impacts caused by high-speed operation, but also need to cope with the challenges of complex climate environments. Traditional fasteners are no longer able to meet the technological needs of modern high-speed rail, which has prompted the industry to accelerate its transformation towards high-end fasteners with high strength, corrosion resistance, and anti loosening properties. Industry analysis shows that the high-speed rail fastener market is presenting three major development trends: firstly, as operating speeds move towards 400 kilometers per hour, the fatigue resistance requirements for fasteners have increased by more than 50%; Secondly, under the “dual carbon” target, the demand for lightweight materials has led to an average annual growth rate of 15% in the application of new materials such as aluminum alloys and titanium alloys; Thirdly, the popularization of intelligent operation and maintenance systems has driven the market demand for intelligent fasteners with status monitoring functions to reach a compound annual growth rate of 20%. These trends are reshaping the entire industrial chain landscape.
