Ductile iron manhole covers is a product of, ductile spherical graphite obtained through ball and bred deal effectively improve the mechanical properties of cast iron, especially to improve the ductility and toughness, resulting in higher strength than steel. Ductile iron is the 1950s developed a high-strength cast iron materials, its overall performance is close to steel, is based on its excellent performance, has been successfully used to cast some complicated force, strength, toughness, wear resistance require a higher part. Ductile iron has been behind the rapid development of gray cast iron, cast iron material is widely used. The so-called "iron and steel", mainly referring to ductile iron.
