Abstract
A method of treating steel sheets which have good corrosion resistance after forming, which comprises coating a steel sheet with a solution which contains: PA1 (a) water-soluble or water-dispersible lithium silicate at a concentration of 2 to 250 g/l, which lithium silicate is a mixture of silicic acid or silicate and lithium salt in a molar ratio of 20:1 to 1:1. PA1 (b) at least one water-soluble or water-dispersible saturated or unsaturated fatty acid compound, higher alcohol wax, polyethylene type resin, fluorine type resin or silicone type resin at a concentration of 1 to 250 g/l.
