Abstract

Ferritic stainless steel, comprising the following Chemical elements expressed in percentage by weight: -Cr 14.0-20.0 -Al 0.50-1.50 -Zr 0.10-0.50 -Si 0.30-1.50 -Ti 0.10-0.35 -Nb 0.25-0.55 -C<0.035 -N<0.035 provided that the content of Ti, Nb, C and N satisfy the following relation: %Ti+%Nb/1.94>9 (%C+%N) and substantially iron q. s. to 100. This steel may also comprise Yttrium and/or rare earth elements in a percentage by weight comprised in the range 0.10-0.30. The invention also encompasses products manufacturable with the steel of the invention, in particular vehicle exhaust manifold systems. Figure (I) shows a cyclic oxidation test carried out at 1000° C. on samples having the composition of an embodiment of the steel according to the invention.
