STEEL SHEET FOR PORCELAIN ENAMELING, ITS MANUFACTURING METHOD, ENAMELED PRODUCT AND ITS MANUFACTURING METHOD

Document Type and Number:

Japanese Patent JP2004107755

Kind Code:

A

Abstract:

To provide a steel sheet for porcelain enameling by which excellent adhesion of enamel can be obtained by only one-coat enameling using a Ti-added steel sheet, its manufacturing method, an enameled product and its manufacturing method.

Co-Mo alloy plating is applied to the Ti-added steel sheet having a composition consisting of, by weight, ≤0.01% C, ≤0.5% Mn, ≤0.04% P, ≤0.04% S, 0.01 to 0.50% Ti and the balance Fe with inevitable impurities. Subsequently, heat treatment is carried out to produce the steel sheet for porcelain enameling in which the amounts of Co, Mo and Fe existing at the surface of the steel sheet are regulated to values within prescribed ranges, respectively. Then one coat of a glaze is applied to the steel sheet, followed by firing.
