S3555j0W steel tau dav siv nyob rau hauv high- ceev kev tsheb ciav hlau bogies, vuam ceev cov ciav hlau, vuam, bolting thiab riveting qhov chaw. S355j0 hlau phaj txhim kho lub peev xwm tiv thaiv cov atmospheric corrosion ntawm qhov kub kub.
Txhawm rau kom ua tiav corrosion tsis kam, qee cov alloy hais tau ntxiv, xws li: P, hauv ntau lub huab cua yog tsim ntawm cov hlau nthwv dej
