Deteriorating Buried Infrastructure Management

was the introduction of ductile iron pipe in the late 1960’s. Ductile iron differs from cast iron in that its graphite form is spheroidal, or nodular, instead of the flake form found in cast iron. This change in graphite form is accomplished by adding an inoculant, usually magnesium, to molten iron of appropriate composition during manufacture.

What is Ductile Iron? - Willman Industries

The tensile strength of cast iron is 20,000 – 60,000 psi while ductile iron starts at 60,000 psi and can go to 120,000 psi. The yield strength for ductile iron is generally 40,000 – 90,000 psi but the yield strength of cast iron is so low it is considered not measurable. Let us put strength in a different way.

DUCTILE IRON DATA FOR ENGINEERS

but most successful member of a truly ancient family, Ductile Iron has suffered from an abundance of myths and a lack of information. "Cast iron is brittle." is an outdated but widely held truism which mistakenly implies that all cast irons are the same, and none are ductile. In fact, Ductile iron is far more than a cast iron which is ductile.

Ductile iron - Wikipedia

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 graphite-rich cast iron discovered in 1943 by Keith Millis. While most varieties of cast iron are weak in tension and brittle, ductile iron has much more impact and fatigue resistance, due to its nodular graphite inclusions.
