Ductile iron

Ductile iron

Ductile iron refers to the cast iron whose graphite is spherical after the molten iron is treated with spheroidizing agent.                         The Ductile iron presents the as cast structure of graphite, ferrite and pearlite under the microscope.

The spheroidization rate is an important standard to evaluate the quality of castings.

material advantage

Ductile Cast Iron

Also known as spheroidal graphite cast iron, ductile cast iron is a form of metal that exhibits significant fatigue, impact, and corrosion resistance.

Compared to other types of iron, ductile cast iron, which typically has a carbon concentration of 0.08% to 0.60%, ductile cast iron has a substantially higher carbon content (3.0% to 3.9%). This distinction explains why ductile iron responds to corrosion in a different way.

A graphitic layer is present in ductile iron. Graphite builds up as a graphitic coating on the metal’s surface when corrosion starts. The following corrosion and galvanic behavior of ductile iron are influenced by the adhesion and porosity of this layer.
