<p>An aluminum coated low alloy low-carbon steel sheet material having increased resistance to oxidation at elevated temperatures of about 1,500 DEG F which is formed by incorporating in a low-carbon steel before rolling and hot-dip aluminum coating an amount of aluminum between about 0.5 and 2 percent by weight and silicon in an amount between about 0.5 and 2 percent by weight, with the ratio of aluminum of silicon being between about 0.5 to about 1.5. Metals which have strong carbide and oxide forming properties, particularly chromium and titanium, can also be used in combination with the low-carbon aluminumsilicon steel in an amount which preferably does not exceed about 2 percent by weight of the steel.</p> |
