3D Ductile Cast Iron

Overview

3D Cast Iron is a ductile iron that has a stock grade of 3D and is otherwise known as spheroidal graphite or nodular iron. The material is high strength ductile and more readily machined than other styles of cast iron. Its properties include being highly elastic and resistant to impact and is suitable for applications involving thermal and mechanical shock. 3D Ductile Iron is also the preferred choice for making hydraulic cylinder components.
