PURPOSE:To obtain an aluminum steel sheet superior in corrosion resistance by applying molten aluminum plating to a steel sheet incorporating specified ratios of C, Cr, Mn, Si, N, Al to steel. CONSTITUTION:The steel sheet consisting <=0.01% C, 3-18% Cr, 0.1-1.5% Mn, <=0.1% Si, <=0.004% N, 0.005-0.08% Al and the balance iron with inevitable impurities subjected to molten aluminum plating. It is preferable to regulate to >=about 0.3% and <= about 0.2% a P and S respectively. In this way, the aluminum plate steel sheet superior in heat resistance and useful for exhaust system material for automobile having improved corrosion resistance is obtained. |
