2018-01-31
By the end of 2017, NISCO’s fasteners produced with the high-speed spring steel have been applied to 17 high-speed railway lines in China, accounting for 25% of the domestic market, ranking top in share and performance domestically. Meanwhile, NISCO took the lead in drafting the national standard "Hot-Rolled Wire Rod for Spring Steel of High Speed ​​Railway Fasteners".
Due to the high speed of trains, fasteners must be of sufficient buckling force and a certain elastic range with sufficient strength and durability. Besides, the finished surface of spring steel must bear "zero" defect. With many experiments, NISCO have been optimizing and upgrading the technology from compositional design to controlled rolling and controlled cooling, meeting customers’ requirements with quick application into high speed rail. Through hard work in 2007, the spring steel of high-speed railway developed by NISCO passed the technical clearance of new products in Jiangsu Province in 2008, with its fatigue life being superior to that of similar products in China. It has premium quality reaching the international advanced level. After 10 years of development, NISCO have formed its own unique R & D system, technical team and production system of high-speed rail steel.
