摘要： The surface of a stainless steel sheet before Fe-coating and the surface of the same stainless steel sheet after Fe-coating are analyzed by X-ray fluorescent analysis to determine the ratio of a fluorescent X-ray intensity I.sub.Cr b ascribable to CF to a fluorescent X-ray intensity I.sub.Fe b ascribable to Fe before Fe-coating, I.sub.Cr b/I.sub.Fe b, and the ratio of a fluorescent X-ray intensity I.sub.Cr a ascribable to Cr to a fluorescent X-ray intensity I.sub.Fe a ascribable to Fe after Fe-coating, I.sub.Cr a/I.sub.Fe a, and the resulting values are substituted in the following equation to calculate an Fe coating weight W (g/m.sup.2).W=(I.sub.Cr b/I.sub.Fe b-I.sub.Cr a/I.sub.Fe a)/Cwherein C represents a proportional constant determined by the type of steel of a stainless steel sheet.
