What is the difference in price between grey iron and ductile iron?
The iron content of pig iron is not more than 1.7%, and carbon is in the form of Fe3C. It is hard and crisp, and the fracture surface is white. Mainly used as raw material for steelmaking and malleable iron
Casting pig iron content is 1.25~3.6%. Carbon is present in graphite. The fracture surface is grey. Soft and easy cutting. Mainly used to produce all kinds of cast iron raw materials, such as bed, box and so on.
Iron carbon content is greater than 2% (2.11%) of the iron carbon alloy industry, iron carbon content is generally 2.5%~4.0%, Si, Mn, S and P, and other elements, is the use of iron ores in blast furnace smelting products.Iron and pig iron are divided into iron numbers according to the content of silicon (Si), grouped by manganese (Mn), classified according to the content of phosphorus (P), and classified according to the content of sulfur (S).
