PROBLEM TO BE SOLVED: To provide ferritic stainless steel in which machinability is improved without particularly deteriorating toughness and ductility and also to provide its manufacturing method. SOLUTION: The ferritic stainless steel has a composition consisting of, by mass,≤0.15% C,≤1.00% Si,≤1.50% Mn, 12 to 30% Cr,≥0.010% S and the balance Fe with inevitable impurities and further containing, if necessary, 2.0 to 6.0% Al. Moreover, the width of sulfides is made to≤3μm. COPYRIGHT: (C)2006,JPO&NCIPI
