FERRITIC STAINLESS STEEL FOR AUTOMOTIVE EXHAUST SYSTEM WITH EXCELLENT CORROSION RESISTANCE FOR WATER CONDENSATION AND FORMABILITY AND THE METHOD OF MANUFACTURING THE SAME

The present invention relates to ferritic stainless steel having excellent corrosion resistance against condensate and moldability, wherein the ferritic stainless steel is capable of being manufactured in an economically advantageous manner without adding expensive alloying elements. Provided is ferritic stainless steel having excellent corrosion resistance against condensate and moldability, and comprising C greater than 0 and less than or equal to 0.01 wt%, 9 to 13 wt% of Cr, 0.5 to 1.0 wt% of Si, Mn greater than 0 and less than or equal to 0.5 wt%, P greater than 0 and less than or equal to 0.035 wt%, S greater than 0 and less than or equal to 0.01 wt%, 0.15 to 0.5 wt% of Ti, N greater than 0 and less than or equal to 0.01 wt%, 0.05 to 0.5 wt% of Sn, and remaining amount of Fe and inevitable impurities, wherein Sn is 10 times more concentrated on the surface portion of the stainless steel than on the base portion.
