Further, the size of MnS as a precipitate in the steel is regulated to a value not exceeding a diameter of 0.15μm. Corrosion resistance is deteriorated with the increase of the number of MnS in the steel. The amount of MnS is increased with the increase of the amount of S. When the amount of S is <=0.010% and the size of MnS is <=0.15μm, the maximum depth of pitting corrosion is lessened and corrosion resistance is improved. Moreover, when the amount of S is <=0.010%, ductility is improved. Al is an element necessary to reduce solid- solution N in the steel and, in order to precipitate N in the steel as AlN, an amount of 0.010% is required as a minimum.
