A ferritic stainless steel characterized by superior crevice and intergranular corrosion resistance. The steel consists essentially of, by weight, up to 0.08% carbon, up to 0.06% nitrogen, from 25.00 to 35.00% chromium, from 3.60 to 5.60% molybdenum, up to 2.00% manganese, up to 2.00% nickel, up to 2.00% silicon, up to 0.5% aluminum, up to 2.00% of elements from the group consisting of titanium, zirconium and columbium, balance essentially iron. The sum of carbon plus nitrogen is in excess of 0.0275%. Titanium, zirconium and columbium, are in accordance with the following equation: %Ti/6+%Zr/7+%Cb/8>/=%C+%N .
