Abstract
A heat resisting ferritic stainless steel which com-prises, by weight, up to 0.03 % of C, from 0.1 to 0.8 %
of Si, from 0.6 to 2.0 % of Mn, up to 0.006 % of S, up to 4 % of Ni, from 17.0 to 25.0 % of Cr, from 0.2 to 0.8 %
of Nb, from 1.0 to 4.5 % of Mo, from 0.1 to 2.5 % of Cu, and up to 0.03 % of N, and optionally one or more of appropriate amounts of Al, Ti, V, Zr, W, B and REM, the balance being Fe and unavoidable impurities, wherein the alloying elements are further adjusted so that the ratio of Mn%/S% is not less than 200, [Nb] defined by the equa-tion: [Nb] - Nb% - 8 (C% + N%) is not less than 0.2, and (Ni% + Cu%) is not more than 4. The stainless steel ac-cording to the invention is suitable for use in con-strutting an exhaust gas path-way of an automobile, par-ticularly, a path-way from an engine to a converter, which is exposed to high temperatures, and which requires an improved low temperature toughness and a high resis-tance to weld cracking due to high temperatures.
