摘要： Tin free steel having three layers consisting of a bottom layer of metallic chromium, a middle layer of metallic nickel and a top layer of hydrated chromium oxide on a steel base, and a method for the continuous production of this tin free steel which comprises; (a) chromium plating a steel base to form a layer of metallic chromium and hydrated chromium oxide; (b) nickel plating the chromium plated steel base by using a nickel plating electrolyte sufficiently acidic to dissolve the hydrated chromium oxide and (c) forming a hydrated chromium oxide layer on the chromium plated nickel plated steel base.Instead of step (b) in the above method, a cathodic treatment in an acidic solution can be carried out for the removal of the hydrated chromium oxide formed during chromium plating, and thereafter nickel plating can be carried out.This tin free steel is useful for producing welded can bodies at high speed without removing the plated layer in the welded part, since it has an excellent weldability.

摘要： A method for producing a thin tin and nickel plated steel sheet having a surface structure in which the distribution of numerous nodules of metallic tin are observed by using an electron microscope on an iron-tin-nickel alloy layer formed on a steel sheet which comprises electroplating nickel on the steel sheet which is anodically treated in an alkaline electrolyte with a pH of above 10 followed by electrotinplating the nickel plated steel sheet, reflowing, quenching, and then chromate treating the tin and nickel plated steel sheet.This tin and nickel plated steel sheet is suitable for welded can materials since it is excellent in corrosion resistance after lacquering and weldability.

摘要： A polyethylene film is heat bonded to a metal sheet provided with a layer of hydrated chromium oxide, and possibly a layer of metallic chromium under the oxide layer. The laminated metal sheet is then rapidly quenched, and the polyethylene laminate is irradiated with an electron beam, gamma rays, or X-rays. Alternatively, the polyethylene film may be irradiated prior to lamination. The laminated metal sheet exhibits excellent resistance to steam and hot water and does not delaminate during forming operations such as can-making.

摘要： A polyester resin film laminated metal sheet having a metal sheet and a polyester resin film on at least one surface. The polyester resin film is 41 to 58 weight percent polybutyelene terephthalate and 42 to 59 weight percent polyethylene terephthalate. This composition provides the polyester resin film laminated metal sheet with an improved resistance to milky discoloration during retort treatment.
