Zusammenfassung:A ferritic stainless steel having improved magnetization is disclosed. The disclosed ferritic stainless steel comprises, on the basis of wt%, 0.01% or less (excluding 0) of C, 0.003% or less (excluding 0) of N , 15-18% of Cr, 0.3-1.0% of Mn, 0.2-0.3% of Si, 0.005% or less (excluding 0) of Al , 0.005% or less (excluding 0) of Ti , and the balance of Fe and inevitable impurities, and satisfies the following equation (1). Equation (1): (Ti+Al+8*(C+N)/Mn) ≤ 0.3, wherein Ti, Al, C, N and Mn means the amount of each element (wt%). La présente invention concerne un acier inoxydable ferritique ayant une aimantation améliorée. L'acier inoxydable ferritique de l'invention comprend, sur la base de % en poids, 0,01 % ou moins (à l'exclusion de 0) de C, 0,003 % ou moins (à l'exclusion de 0) de N, de 15 à 18 % de Cr, de 0,3 à 1,0 % de Mn, de 0,2 à 0,3 % de Si, de 0,005 % ou moins (à l'exclusion de 0) d'Al, 0,005 % ou moins (à l'exclusion de 0) de Ti, et le reste de Fe et d'impuretés inévitables, et satisfait l'équation (1) suivante. Équation (1) : (Ti + Al + 8 * (C + N)/Mn) ≤ 0,3, où Ti, Al, C, N et Mn représentent la quantité de chaque élément (% en poids). 자화특성이 향상된 페라이트계 스테인리스강이 개시된다. 개시된 페라이트계 스테인리스강은 중량%로, C: 0.01% 이하(0은 제외), N: 0.003% 이하(0은 제외), Cr: 15 내지 18%, Mn: 0.3 내지 1.0%, Si: 0.2 내지 0.3%, Al: 0.005% 이하(0 제외), Ti: 0.005% 이하(0 제외), 나머지는 Fe 및 불가피한 불순물을 포함하고, 하기 식 (1)을 만족한다. 식 (1): (Ti+Al+8*(C+N)/Mn) ≤ 0.3 (여기서, Ti, Al, C, N 및 Mn은 각 원소의 함량(중량%)을 의미한다.)
