A606-4 contains additional alloying elements and provides a level of corrosion resistance substantially better than that of carbon steels with or without copper addition. When properly designed and exposed to the atmosphere, A606-4 can be used bare (unpainted) for many applications. Three Types of ASTM A606 Steel ASTM A606 Steels have enhanced atmospheric corrosion resistance and are supplied in three types: Type 2 contains 0.20 % minimum copper based on cast or heat analysis (0.18 % minimum Cu for product check). Type 4 and Type 5 contain additional alloying elements and provide a level of corrosion resistance that is significantly better than that of carbon steels with or without copper addition. When properly exposed to the atmosphere, Type 4 and Type 5 steels can be used in unpainted conditions for many uses. Where Does Orange Color Finish Come From in A606-4? The orange-brown finished color in A606-4 comes mainly from the copper content. With 5% copper in the alloy mix, the copper immediately comes to the top as the patina process begins. Additionally, the copper along with manganese, silicon, and nickel content in A606-4 creates that protective layer as the material continues to patina. Standard carbon steel will rust but it will not have the beautiful colors that come from A606-4.
