<P>PROBLEM TO BE SOLVED: To provide a surface treating solution capable of inhibiting scale generation on steel by heat treatment and capable of manufacturing heat treating steel products excellent in weldability and coating adhesibility, and to provide a method for manufacturing the heat treating steel products using the surface treating solution. <P>SOLUTION: This surface treating solution comprises an inorganic binder and a metal pigment in a solvent. The inorganic binder is at least one selected from the group consisting of silica, titania, zirconia, an organosilicon compound, an organotitanium compound and an organozirconium compound. The metal pigment comprises, based on the total amount of the metal pigment and the inorganic binder, (a) 5-20 mass% of a zinc oxide powder, (b) 15-60 mass% of a metal powder resistant to oxidation at a high temperature and (c) 10-25 mass% of a metal foil. The total content of the metal pigment is 50-75 mass% based on the total amount of the metal pigment and the inorganic binder. <P>COPYRIGHT: (C)2010,JPO&INPIT |
