Ductile Iron Casting Many of the engineering properties of steel can be realized with Ductile Iron Casting. It has the ability to be cast in heavier sections and can be used to produce larger castings than malleable iron. Ductile Iron Casting has replaced forgings, weldments and steel castings in an ever increasing number of applications. T
Typical Applications for Ductile Iron Casting:
Ductile Iron Casting is particularly well suited for Valves, Pump - Gears and Rollers, Spring Hangers, Suspension Parts, Wheel Hubs, Bearing Caps, Hardware, Universal Joints, Threadless Connectors and Flanges, Various Automotive and Agricultural Items.
Advantages of Ductile Iron Casting:
Ductile Iron Casting provides Higher Tensile Strength, Less Deflection Under Load Conditions, No Straightning Required in Most Instances, No Problems With Hot Tears and Cracks, Good Machinability, Easier Feeding of Difficult Designs
