Casting of the carbon in cast iron with flake graphite form, its fracture is gray, usually also called gray iron.Due to graphite soft, with lubrication, thus casting pig iron has good cutting, wear-resisting and casting performance.But its tensile strength is not enough, so can not be forged, can only be used in the manufacture of all kinds of castings, such as casting a variety of machine tool bed, iron pipe, etc.
Pig iron generally refers to the carbon content in 2 ~ 4.3% of the iron alloy.Also known as cast iron.In addition to carbon in cast iron, but also contains silicon, manganese, and small amounts of sulfur, phosphorus, etc., it may cause cannot be forged.Casting of the carbon in cast iron with flake graphite form, its fracture is gray, usually also called gray iron.Due to graphite soft, with lubrication, thus casting pig iron has good cutting, wear-resisting and casting performance.But its tensile strength is not enough, so can not be forged, can only be used in the manufacture of all kinds of castings, jiangnan cast all such as casting a variety of machine tool bed, iron pipe, etc.
