Title (EN) STEEL SHEET FOR CANS AND PRODUCTION METHOD FOR STEEL SHEET FOR CANS
(FR) TÔLE D'ACIER POUR CANETTES ET PROCÉDÉ DE FABRICATION D'UNE TÔLE D'ACIER POUR CANETTES
(JA) 缶用鋼板およびその製造方法
Abstract:
(EN) Provided is a steel sheet for cans that has excellent weldability and an excellent surface appearance. Also provided is a production method for the steel sheet for cans. The steel sheet for cans has, on the surface thereof, in order from the steel sheet side, a chromium metal layer and a hydrous chromium oxide layer. The chromium metal layer is deposited in an amount of 50-200 mg/m2, and the hydrous chromium oxide layer is deposited in an amount of 3-15 mg/m2 in terms of chromium. The chromium metal layer includes: a flat chromium metal layer that has a thickness of at least 7 nm; and a granular chromium metal layer that includes granular protrusions that are formed on the surface of the flat chromium metal layer. The maximum grain size of the granular protrusions is 150 nm or smaller. The number density of the granular protrusions per unit area is 10/μm 2 or higher.
(FR) Cette invention concerne une tôle d'acier pour canettes qui présente une excellente aptitude au soudage et un excellent aspect de surface. L'invention concerne en outre un procédé de fabrication de la tôle d'acier pour canettes. La tôle d'acier pour canettes possède, sur sa surface, dans l'ordre à partir du côté de la tôle d'acier, une couche de métal chromé et une couche d'oxyde de chrome hydraté. La couche de métal chromé est déposée en une quantité de 50 à 200 mg/m2, et la couche d'oxyde de chrome hydraté est déposée en une quantité de 3 à 15 mg/m2 en termes de chrome. La couche de métal chromé comprend : une couche plane de métal chromé qui présente une épaisseur d'au moins 7 nm; et une couche granulaire de métal chromé qui comprend des protubérances granulaires qui sont formées sur la surface de la couche plane de métal chromé. La taille maximale des grains des protubérances granulaires est inférieure ou égale à 150 nm. La densité en nombre des protubérances granulaires par unité de surface est supérieure ou égale à 10/μm2.
(JA) 溶接性および表面外観に優れる缶用鋼板およびその製造方法を提供する。上記缶用鋼板は、鋼板の表面に、上記鋼板側から順に、金属クロム層およびクロム水和酸化物層を有し、上記金属クロム層の付着量が、50~200mg/m2であり、上記クロム水和酸化物層のクロム換算の付着量が、3~15mg/m2であり、上記金属クロム層が、厚さが7nm以上である平板状金属クロム層と、上記平板状金属クロム層の表面に形成された粒状突起を有し、上記粒状突起の最大粒径が150nm以下であり、かつ、上記粒状突起の単位面積あたりの個数密度が10個/μm2以上である粒状金属クロム層と、を含む。
