The characteristics of as cast high strength and high plasticity pearlitic ductile iron are as follows: (1) Compared with ordinary

At present, there are two kinds of as cast high strength and high plasticity ductile iron in China： The first

Although the metallurgical quality of molten iron is affected by many factors, foundry workers have found the quantitative index of

Cast pig iron, ferrosilicon, ferromanganese, ferromolybdenum, pure copper and ferroniobium were used as raw materials. According to the target chemical

Nodular cast iron is widely used in automobile parts, such as wheel hub, differential case, bracket, steering knuckle, main cover,

As we all know, the formation of shrinkage cavity and porosity of ductile iron is determined by its solidification characteristics,

High strength ductile iron is an important engineering structural material. Although it came out late, it has good machinability and

The necking riser is used at the top of the spent fuel container, and the riser is designed according to
