    • A highly corrosion resistant aluminized steel sheet comprising a steel substrate consisting essentially of, in % by weight, up to 0.08% of C, from 0.10 to 1.50% of Si, up to 0.50% of Mn, from 0.10 to 0.50% of Cu, preferably from 0.10 to 0.50% of Ni and/or from 0.30 to 5.0% of Cr, the balance being Fe and unavoidable impurities, having on its surfaces hot dip coated aluminum layers. Such an aluminized steel sheet is very resistive against severe corroding conditions involving repeated cycles of exposure to alkaline and acidic drains of an automobile exhaust gas and elevated temperatures, and therefore, is very suitable for the manufacture of parts, such as a muffler, of an automobile exhaust gas system.
