ABSTRACT:
A ferritic stainless steel for automobile exhaust gas passage components comprises, in mass percent, C: not more than 0.03%, Si: not more than 1%, Mn: not more than 1.5%, Ni: not more than 0.6%, Cr: 10-20%, Nb: not more than 0.5%, Ti: 0.05-0.3%, Al: more than 0.03% to 0.12%, Cu: more than 1% to 2%, V: not more than 0.2%, N: not more than 0.03%, B: 0.0005-0.02%, O: not more than 0.01%, and the balance of Fe and unavoidable impurities, whose composition satisfies the relationships Nb≧8 (C+N) and 0.02≦Al−(54/48))≦0.1. The steel enables fabrication of automobile exhaust gas passage components that are excellent in high-temperature strength and weld toughness, and offers a wide range of freedom in selecting suitable pipe-making conditions.
