In casting production, we often hear foundry manufacturers say that this is gray cast iron, that is ductile iron, many times we are difficult to distinguish.

As a common casting defect in production and processing, the fracture of casting parts should be paid attention to by foundry manufacturers.

There are many kinds of heat treatment processes for casting parts, which are generally composed of three stages: heating, insulation and cooling. However, the deformation of casting parts often occurs in the process of hot working.
