Ductile Iron. Ductile iron, also known as ductile cast iron, nodular cast iron, spheroidal graphite iron, spheroidal graphite cast iron and SG iron, is a type of cast iron invented in 1943 by Keith Millis. While most varieties of cast iron are brittle, DI has much more impact and fatigue resistance, due to its nodular graphite inclusions.

Spheroidal graphite (SG) cast iron was discovered in the 1948. However, lf coke (which is high in sulfur) had not been used for melting iron and if high purity ores had been used, then ductile iron would have been accepted as the normal form of iron, with flake graphite iron only being discovered much later as an accident of adding S and O.
