Research shows that almost all defects of ductile iron are related to spheroidizing agent.
For metal castings, our more commonly used surface treatment methods are: mechanical polishing, chemical treatment, surface heat treatment, and sprayed surface.
The process of pouring cast steel is a very important step.
In order to ensure the consistency of casting quality, inoculation treatment is essential.
Commonly used heat treatment methods for ductile cast iron.
Cast steels have high design and manufacturing flexibility and can find extensive applications.
