Title
(EN) FERRITIC STAINLESS STEEL SHEET WITH EXCELLENT WORKABILITY AND PROCESS FOR PRODUCING SAME
(FR) FEUILLE D'ACIER INOXYDABLE FERRITIQUE AYANT UNE EXCELLENTE APTITUDE AU FAÇONNAGE
(JA) 加工性に優れたフェライト系ステンレス鋼板およびその製造方法
Abstract
(EN) A ferritic stainless steel sheet having excellent ridging resistance, characterized by containing, in terms of mass%, 10-30% Cr, 0.005-1% Sn, 0.001-0.1% C, 0.001-0.1% N, 0.01-3.0% Si, 0.01-3.0% Mn, 0.005-0.1% P, and 0.0001-0.01% S, with the remainder comprising Fe and unavoidable impurities. The steel sheet is further characterized in that the X-ray diffraction intensity for the {100}<012> orientation at a depth of t/4 (t is the sheet thickness) from the surface layer is 2 or more.
(FR) L'invention concerne une feuille d'acier inoxydable ferritique ayant une excellente résistance à la formation de rides, présentant la caractéristique de contenir 10 à 30% de Cr, 0,005 à 1% de Sn, 0,001 à 0,1% de C, 0,001 à 0,1% de N, 0,01 à 3,0% de Si, 0,01 à 3,0% de Mn, 0,005 à 0,1% de P, et 0,0001 à 0, 01% de S, le reliquat comrpenant du fer et des impuretés inévitables. La feuille d'acier se caractérise également en ce que l'intensité de la diffraction par rayons X pour l'orientation {100}<012> à une profondeur de t/4 (t représentant l'épaisseur de la feuille) depuis la couche de surface est égale ou supérieure à 2.
