Abstract

Ferritic steel alloyed with a balanced quantity of chromium, aluminium and reactive elements and that has the following composition (in % by weight): Ni up to 1 Cr 15-25 Al 0,75-3,7 Si max 0,6 Mo and/or W 0-3 Ti and/or Nb 0-1 Cup to 0,2 N up to 0,2 one or more of the reactive elements Zr, Hf and REM >0 balance iron and normally occurring impurities, wherein the equation Cr+3AI ≥ 26 is satisfied. The ferritic stainless steel is suitable for use as substrate material in catalytic converters for diesel engines in heavy vehicles at temperatures in the interval of 600-900 °C and a specific relation between the content of chromium and aluminium being satisfied.
