Ductile iron is a kind of high strength cast iron material, its comprehensive performance is close to steel, it is based on its superior performance, has been successfully used in casting some complex loading, requiring higher strength, toughness and abrasion resistance parts. Ductile iron has been rapidly developed to be second only to gray cast iron and widely used in cast iron. The so-called "iron steel" mainly refers to ductile cast iron.
