Abstract

The invention concerns a method for phosphating a steel band or a steel band galvanized or alloy-coated on one side or both sides by spraying or dipping for a period ranging from 2 to 15 seconds using an acid, zinc and manganese-containing phosphating solution at a temperature ranging from 40 to 70 DEG C. Said method is characterized by a phosphating solution containing 1 to 4 g/l zinc ions, 0.8 to 3.5 g/l manganese ions, 10 to 30 g/l phosphate ions, 0.1 to 3 g/l free, ionic or bound hydroxylamine, and no more than 1 g/l nitrate ions, a free acid content ranging from 0.4 to 4 points and a total acid content ranging from 12 to 50 points. The phosphating solution contains optionally 0.8 to 3.5 g/l nickel or 0.002 to 0.2 g/l copper.
