Iron fence with pig iron or ductile iron?
According to the different form of carbon in pig iron, it can be divided into several kinds, such as steelmaking pig iron, casting pig iron and nodular cast iron. Pig iron performance: pig iron is hard, wear-resisting, casting good, but pig iron is crisp, can not forge.There are three kinds of pig iron. Ductile iron is one of them. Do you think it's the same?.
Pig iron is an alloy of iron and carbon carbon content more than 2%, pig iron carbon content is generally in 2.5%--4%, including C, SI, and Mn, S, P and other elements, is the use of iron ores in blast furnace smelting products.
Is not good, with forged steel, because iron and cast iron is one of the properties that are very coarse, and slightly oh you deliberately short easy to rust, life is very short, only forging just made out of life, and not easily broken, the surface is smooth, is among the most well with iron material
