Hot Selling Stainless Steel Sand Casting Foundry – Nodular Cast Iron Sand Casting Foundry – RMC Foundry Detail:

OEM Custom Nodular Cast Iron Sand Castings from China Iron Foundry. CNC machining services are also available from our machining factory.

Ductile cast iron, which is represent a group of cast iron, also called nodular iron. Nodular cast iron obtains nodular graphite through spheroidization and inoculation treatment, which effectively improves the mechanical properties of the cast iron, especially the plasticity and toughness, so as to obtain higher strength than carbon steel.

Nodular iron castings have better shock absorption performance than carbon steel, while carbon steel castings have much better weldability. And to some extent, the ductile iorn castings could have some performances of resistanting wear and rust. So the ductile iron casting could be used for some pump housings or water supply systems. However, we still need to make precautions for protecting them from wearing and rust.

Ductile iron is not a single material but is part of a group of materials which can be produced to have a wide range of properties through control of the microstructure. The common defining characteristic of this group of materials is the shape of the graphite. In ductile irons, the graphite is in the form of nodules rather than flakes as it is in grey iron. The sharp shape of the flakes of graphite create stress concentration points within the metal matrix and the rounded shape of the nodules less so, thus inhibiting the creation of cracks and providing the enhanced ductility that gives the alloy its name.

So generally speaking, if the ductile iron could meet your requirements, the ductile iron could be your first choice, instead of carbon steel for your castings.
