Abstract (en)
[origin: EP3434811A1] A chemical treatment steel sheet includes a steel sheet, an Fe-Sn alloy layer which is formed on at least one surface of the steel sheet, a Sn layer which is formed on the Fe-Sn alloy layer and contains Sn in which a total amount of Sn contained in the Fe-Sn alloy layer and the Sn layer is 0.10 to 30.0 g/m 2 , and a chemical treatment layer which is formed on the Sn layer and contains a Zr compound in which an amount of Zr contained therein is 1.0 to 150 mg/m 2 , a phosphate compound in an amount of P contained therein is 1.0 to 100 mg/m 2 and an Al compound in an amount of Al contained therein is 0.10 to 30.0 mg/m 2 .
