PURPOSE: A ferritic stainless steel alloy for exhaust manifold with improved oxidation resistance even at high temperature compared to existing ferritic stainless steel alloy is provided. CONSTITUTION: The ferritic stainless steel alloy for exhaust manifold comprises a principal constituent of iron (Fe), 14.0 to 16.0 wt.% of chromium (Cr), 0.5 to 4.0 wt.% of silicon (Si), 0.30 to 1.0 wt.% of niobium (Nb), 0 to 0.8 wt.% of copper (Cu), 0.05 to 0.06 wt.% of manganese (Mn), 0 to 0.2 wt.% of titanium (Ti), 0 to 0.03 wt.% of phosphorus (P), 0 to 0.02 wt.% of sulfur (S), 0 to 0.015 wt.% of carbon (C) and 0.05 to 0.5 wt.% of nitrogen (N).
