A highly corrosion resistant chromium-containing steel has corrosion resistance and oxidation resistance comparable or superior to those of low Cr-stainless steel (Cr content: 11-13% by weight), and excellent intergranular corrosion resistance not attainable in existing chromium containing steels. However, the steel has such a low Cr content that it is not classified as a stainless steel. A preferred composition on a weight % basis, is: C: 0.015% or less, Si: from more than 1.0% to 2.0%, Mn: 0.5% or less, P: 0.05% or less, S: 0.01 or less, Ni: 0.015% or less, provided that sum of the C content and the N content (C+N): 0.020% or less. Ti: from more than 0.30% to 0.50% in which the contents for Cr, Ti, C and N, that is, [Cr], [Ti], [C] and [N] satisfying the following relation: [Ti]/([C]+[N])≧64−4×[Cr], balance of Fe and incidental impurities.
