Zusammenfassung: | The disclosed specification relates to a ferritic stainless steel having improved formability by controlling the average grain diameter through alloy components and manufacturing processes and to a method for manufacturing same. A ferritic stainless steel having improved formability, according to one embodiment, may comprise, in percentage by weight: C: 0.0005-0.02%; N: 0.005-0.02%; Si: 0.01-1.0%; Mn: 0.01-1.0%; P: 0.001-0.05%; Cr: 10.0-30.0%; Nb: 0.05-0.5%; Ti: 0.05-0.5%; and the remainder being Fe and inevitable impurities, wherein an Erichsen height may be 6-50 mm.
La présente invention concerne un acier inoxydable ferritique ayant une formabilité améliorée par régulation du diamètre de grain moyen à travers des composants d'alliage et des procédés de fabrication, et un procédé de fabrication de celui-ci. Un acier inoxydable ferritique ayant une formabilité améliorée, selon un mode de réalisation, peut comprendre, en pourcentage en poids : C : 0,0005-0,02%, N : 0,005-0,02%, Si : 0,01-1,0%, Mn : 0,01-1,0% ; P : 0,001-0,05%, Cr: 10,0-30,0%, Nb : 0,05-0,5%, Ti : 0,05 à 0,5% ; et le reste étant du Fe et des impuretés inévitables, une hauteur d'Erichsen pouvant être de 6 à 50 mm.
