STEEL SHEET FOR VITREOUS ENAMELING EXCELLENT IN WORKABILITY AND FISH SCALE RESISTANCE, AND METHOD FOR PRODUCING THE SAME |
摘要 |
ABSTRACT The present invention relates to a steel sheet for Vitreous enameling excellent in enameling properties (bubbling and black spot resistance, enamel adhesiveness and fish scale resistance) and workability, and a method for producing the same, and is characterized in that the steel sheet contains, in mass of, C: 0.010% or less, Mn: 0.03 to 1.3%, Si: 0.03% or less, Al: 0.02% or less, N: 0.0055% or less, P: below 0.035%, and S: over 0.025% to 0.08%; and the density change of the steel sheet from before an annealing to after an annealing at 850 DEG C for 20 hours, in a hydrogen atmosphere is 0.02% or more.
