Ductile Iron is a type of cast iron which is known for its impact and fatigue resistance, elongation, and wear resistance due to the spherical graphite structures in the metal.
Ductile iron castings are much stronger compared to regular cast iron (gray iron). 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.
Ductile iron, obtained by a special magnesium treatment, has an elastic behavior which confers outstanding mechanical properties upon the metal. All the water supply castings, pipes, and fittings, that are made of ductile iron can benefit from its outstanding mechanical properties. Being extremely tough and robust, they can withstand high external loading and changes in their environment without damage: ie, ground movements, pipe undermining or bedding destabilization, without fracturing, cracking or disjointing.
Ductile iron is not just a single material but it is a part of a group of materials which can be produced with a wide range of properties through control of their microstructure. The shape of graphite is the common defining characteristic of this group of materials. In ductile irons, graphite is in the form of nodules rather than flakes as in grey iron.
The mechanical properties of ductile iron, combined with flexible rubber gasket joints, have resulted in the development of robust, flexible pipe systems, capable of withstanding the operating conditions or adverse site conditions without damage. Ductile iron pipes now constitute the best-engineered offer in the market for medium-and large-diameter pipes. Above and beyond the mechanical properties of ductile iron, they can withstand not only high continuous service regimes but also any overpressures and water hammer, without deterioration or effect on the life of the installation.
