Steel sheet for can exhibiting excellent corrosion resistance
First Claim
1. A steel sheet for a beverage can exhibiting excellent corrosion resistance, adhesive property, and weldability, comprising:
- a steel sheet;
an Ni—
Cu alloy plating layer formed on at least one surface of the steel sheet; and
a chromate film layer formed on a surface of the Ni—
Cu alloy plating layer, whereinthe Ni—
Cu alloy plating layer has Ni attached thereto in an amount of from 0.30 g/m2 to 3.0 g/m2, and Cu contained therein in an amount of from 0.5 mass % to 3.8 mass %; and
the chromate film layer has Cr attached thereto in an amount of from 1.0 mg/m2 to 40 mg/m2 in equivalent units of Cr.
