A differential multilayer-coated steel strip having an excellent corrosion resistance, enamel-adhering property, seam weldability and drawability and being useful for the production of cans, comprisingn (A) a steel strip substrate; (1) (B) a first surface coating formed on a surface of the substrate and comprising (a) a plated nickel first base layer (3a) formed on the substrate surface and consisting of from 10 to 5,000 mg/m 2 of plated nickel, (b) a plated tin intermediate layer (4) formed on the first base layer surface and consisting of from 50 to 11,000 mg/m 2 of plated tin, and (c) a chromium-plated first surface layer (5a) formed on the intermediate layer surface and having a weight of from 3 to 50 mg/m 2 , in terms of metallic chromium; and (C) a second surface coating formed on the other surface of the substrate and comprising (d) a plated nickel second base layer (3b) formed on the other surface of the substrate and consisting of from 10 to 5,000 mg/m 2 of plated nickel, and (e) a chromium-plated second surface layer (5b) formed on the second base layer surface and having a weight of from 3 to 50 mg/m 2 , in terms of metallic chromium. |
