Abstract (en)
[origin: EP3190211A1] Provided are a cold-rolled steel sheet having excellent chemical convertibility and excellent corrosion resistance after coating, a method of manufacturing a cold-rolled steel sheet and an automobile member. In the method of manufacturing a cold-rolled steel sheet, first pickling is applied to a steel sheet which is continuously annealed after cold rolling, second pickling is applied to the steel sheet subsequently and, thereafter, neutralizing treatment is applied to the steel sheet using an alkaline solution.
