The phosphatability of low carbon, Ti-added steel sheet produced by continuous annealing was investigated. Portions of the surface of samples that had been ground were found to be inferior in phosphatability because of their excellent corrosion resistance. The addition of Mn or S, especially MnS precipitate, was effective in improving the phosphatability of the samples with the result that, in the phosphating of Ti-added and other steel sheet with superior corrosion resistance, the dissolution of Fe which is the initiating reaction, seems to have the greatest importance.
