Summary: | Disclosed, as a steel sheet having excellent energy-absorbing performance during crushing deformation, is a steel sheet having a specific chemical composition and steel structure, in which the steel sheet surface has multiple steps that have a peak-trough difference exceeding 5.0 μm and that are present at intervals of 2.0 mm or less.
Est divulguée, sous la forme d'une tôle d'acier ayant une excellente performance d'absorption d'énergie pendant la déformation à l'écrasement, une tôle d'acier ayant une composition chimique spécifique et une structure en acier, dans laquelle la surface de tôle d'acier a de multiples marches qui ont une différence de creux -pic dépassant 5,0 μm et qui sont présentes à des intervalles de 2,0 mm ou moins.
圧潰変形時のエネルギー吸収性に優れる鋼板として、所定の化学組成及び鋼組織を有する鋼板であって、板表面において5.0μm超の高低差を有する段差が2.0mm以下の間隔で複数存在する鋼板を開示する。 |
