Title (EN) ZINC-PLATED STEEL SHEET AND PRODUCTION METHOD THEREFOR
(FR) TÔLE D'ACIER ZINGUÉ ET PROCÉDÉ DE PRODUCTION ASSOCIÉ
(JA) 亜鉛系めっき鋼板およびその製造方法
Abstract:
(EN) Provided are: a zinc-plated steel plate that consistently exhibits excellent press-moldability whether the plate is a high strength zinc-plated steel plate or a zinc-plated steel plate of relatively low strength on which complex molding is performed, and which does not generate harmful fumes during welding; and a production method therefor. The plate has an oxide layer on the surface of the zinc-plated steel plate. The oxide layer has an average thickness of at least 20 nm. The oxide layer contains at least 30 mg/m2 of Zn, at least 1.0 mg/m2 of S, and 50 mg/m2 to 1000 mg/m2 of polyethylene particles with an average particle diameter of 5.0 µm or less.
(FR) L'invention concerne : une tôle d'acier zingué qui présente de façon constante une excellente aptitude au moulage à la presse si la plaque est une tôle d'acier zingué à haute résistance ou une tôle d'acier zingué de résistance relativement faible sur laquelle un moulage complexe est réalisé, et qui ne génère pas de fumée nocives pendant le soudage ; et un procédé de production associé. La plaque présente une couche d'oxyde sur la surface de la tôle d'acier zingué. La couche d'oxyde présente une épaisseur moyenne d'au moins 20 nm. La couche d'oxyde contient au moins 30 mg/m2 de Zn, au moins 1,0 mg/m2 de S, et 50 mg/m2 à 1 000 mg/m2 de particules de polyéthylène ayant un diamètre moyen de particule de 5,0 µm ou moins.
(JA) 高強度の亜鉛系めっき鋼板および複雑な成形を施される比較的強度の低い亜鉛系めっき鋼板に対して、安定的に優れたプレス成形性を有し、かつ溶接時に有害ヒュームが発生することのない亜鉛系めっき鋼板およびその製造方法を提供する。 亜鉛系めっき鋼板の表面に酸化物層を有し、酸化物層は、平均厚さが20nm以上であり、酸化物層中には、Znを30mg/m以上、Sを1.0mg/m以上、平均粒子径が5.0μm以下であるポリエチレン粒子を50mg/m以上1000mg/m以下含有する。
