Ductile Iron Sand Castings
Ductile iron sand castings, a process that is an easy and economical method to create basic part shape. The advantages to this process is the cost savings to achieve the basic part shape, and the flexibility in the size of sand castings. Sand castings can be less than one pound to several tons. Another advantage to off shore sourcing for these components is not only will you save on the cost of the casting, but also on the cost of the secondary machining and finishing.
The disadvantage to ductile iron sand castings is the accuracy of the parts. The dimensional accuracy is not as good as other casting methods, and the parts will have a rough surface finish (300-560 RMS). This is why most sand casting will need additional processing to be completed.
Ductile iron was introduced in 1948, a significant metallurgical development. Ductile iron has ductility, as the name implies. It also has far greater strength and impact resistance than gray iron, while retaining it’s corrosion resistance. This makes ductile iron an ideal piping material.
