What is spheroidal graphite cast iron? Willman Industries

The fancy name “spheroidal graphite cast iron” comes from the make-up of ductile iron. We are primarily dealing with iron that is cast in a foundry (obvious, right?). One of the primary ingredients added to the iron is graphite (or carbon) in order to make it stronger. Ductile iron contains 3.2-3.6% carbon.

Materials used in Mining Engineering Castings and

Spheroidal Graphite Cast Irons. Also known as ductile cast iron or nodular cast iron, it was invented in 1943 and, while most cast irons are brittle, these irons have more fatigue strength as well as impact strength. This is due to the nodular graphite inclusion. Here, the graphite is in the form of nodules and not flakes as seen in grey cast
