摘要：
一种容器用钢板，其特征在于，具备：钢板；基底Ni层，其是对所述钢板的至少一面施加以金属Ni量计含有5～150mg/m2的Ni的镀Ni层或镀Fe-Ni合金层来形成的；镀Sn层，其是在所述基底Ni层上施加以金属Sn量计为300～3000mg/m2的镀Sn层、并通过熔锡处理将至少一部分的所述基底Ni层和所述镀Sn层合金化来形成的包含岛状Sn的层；氧化皮膜层，其在所述镀Sn层上形成，并含有氧化锡；和化学转化处理皮膜层，其在所述氧化皮膜层上形成，并至少含有以金属Zr量计为1～500mg/m2的Zr和以P量计为0.1～100mg/m2的磷酸，所述氧化皮膜层含有使该氧化皮膜层还原所需要的电量为0.3～10mC/cm2的量的所述氧化锡。
摘要（英）：
A steel sheet for containers is characterized by comprising: a steel sheet; an underlying Ni layer which is formed by applying a Ni coat or a Fe-Ni alloy coat each containing Ni in an amount of 5 to 150 mg/m<2> in terms of metal Ni content onto at least one surface of the steel sheet; an Sn coat layer which is formed by applying an Sn coat having a metal Sn content of 300 to 3000 mg/2 onto the underlying Ni layer and contains island-shaped Sn regions each produced by alloying at least a part of the underlying Ni layer and at least a part of the Sn coat by a tin melting treatment; an oxide coating film layer which is formed on the Sn coat layer and contains tin oxide; and a chemical conversion treatment coating film layer which is formed on the oxide coating film layer and contains at least Zr in an amount of 1 to 500 mg/m<2> in terms of metal Zr content and phosphoric acid in an amount of 0.1 to 100 mg/m<2> in terms of P content. The steel sheet is also characterized in that the oxide coating film layer contains the tin oxide in such an amount that the quantity of electricity required for the reduction of the oxide coating film layer becomes 0.3 to 10 mC/cm<2>.
