<p><P>PROBLEM TO BE SOLVED: To provide enameled products which have improved tight adhesion of steel substrate and porcelain enamel layer and are excellent in the resistance to sulfuric or hydrochloric acid dew point corrosion; and a glaze. <P>SOLUTION: An enameled product obtained by forming a porcelain enamel layer having a thickness of 50 to 700μm on the surface of a substrate made of a steel containing by mass Cu: 0.05 to 0.5%, Si: 0.1 to 2.0%, Mn: 0.05 to 2.0%, P: 0.005 to 0.10%, S: 0.005 to 0.1%, and C: 0.20% or below with the balance being Fe and unavoidable impurities. The Co oxide content of the porcelain enamel layer is controlled to be 0.01 to 10% in terms of Co and/or the Ni oxide content thereof is controlled to be 0.05 to 20% in terms of Ni. Alternatively the total Ni content of the substrate and the porcelain enamel layer is controlled to be 0.005 to 4.5% based on the whole mass of the enameled product and/or the total Co content thereof is controlled to be 0.008 to 4.0% based thereon. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
