MANUFACTURE OF GALVANIZED STEEL SHEET

PURPOSE:To uniformly apply plating by previously applying Fe-C composite plating to the surface of a steel sheet and thereafter applying galvanizing thereto. CONSTITUTION:The surface of a steel sheet contg. 0.03 to 3% Si is applied with Fe-C composite plating and is then galvanized. Thus, since it i...

Zusammenfassung:	PURPOSE:To uniformly apply plating by previously applying Fe-C composite plating to the surface of a steel sheet and thereafter applying galvanizing thereto. CONSTITUTION:The surface of a steel sheet contg. 0.03 to 3% Si is applied with Fe-C composite plating and is then galvanized. Thus, since it is excellent in coating corrosion resistance, press formability and weldability, the surface plating of a galvanized steel sheet used for a wide industrial field as the material for automobiles, house appliances and building materials can uniformly be applied.
