OREANDA-NEWS. July 20, 2011. A few days ago, the railway vehicle spring steel bar, jointly developed by Wisco and downstream customers, was trial – produced successfully in central bar plant, Wuhan Iron and Steel Company Limited, an arm of Wisco.

Spring steel, especially railway vehicle spring steel, has very high demands on surface quality. The hot rolled bar can only be used after finishing, polishing and flaw detection. To optimize bar product structure and satisfy market needs, Wisco bar steel production-marketing-research team responded quickly, worked in divisions, contacted with users, and signed delivery technical conditions on high-speed trains with special material process units.

According to the technical characteristics for the steel grade, Wisco R&D center task team provocatively cooperated with central bar plant, fabrication division as well as central marketing company of Wuhan Iron and Steel Company Limited, formulated a detailed trial production proposal, and accomplished first run of steel-making, rolling and performance inspection within only 20 days.

The first batch trial products achieved technology standard requirements with all performance indexes. The successful development of spring steel bar will lay a solid foundation for Wisco bar products to apply in high-speed railroading in China.
