Abstract (en)

[origin: EP3434813A1] A chemical treatment steel sheet contains: a steel sheet; a plated layer containing Ni and formed on at least one surface of the steel sheet; a chemical treatment layer containing a Zr compound in which an amount of Zr contained therein is 1.0 to 150 mg/m 2 , a phosphate compound in which an amount of P contained therein is 1.0 to 100 mg/m 2 , and an Al compound in which an amount of Al contained therein is 0.10 to 30.0 mg/m 2 . The plated layer is a Ni-plated layer containing Ni in which an amount of Ni contained therein is 5.0 to 3000 mg/m 2 or a composite plated layer containing Ni in which an amount of Ni contained therein is 2.0 to 200 mg/m 2 and Sn in which an amount of Sn contained therein is 0.10 to 10.0 g/m 2 and having an island-shaped Sn-plated layer formed on a Fe-Ni-Sn alloy layer.
