SG iron is type of cast iron with a high level of ductility. The structure of SG iron has spherical nodules which prevent the occurrence of cracks and increases the ability to withstand distortion. Also called as Ductile Cast Iron, Nodular Cast Iron, Spheroidal Graphite Iron, Spherulitic Cast Iron
Used in multiple industries due to its flexibility to be moulded into complex shapes and light weight when compared to steel casting. They are also fairly resistant to corrosion and can withstand heavy loads. SG iron castings are most commonly used in the following industries...
Due to its light weight and flexible structure, sg iron castings are used in laying railway tracks and in building frames. Since they have high resistance to distortion, they last long without any damage. They also have the ability to withstand heavy loads making them ideal for the railway industry.
SG iron are elastic and have a long service life which make them ideal to be moulded and used as pipes in underground water supply and sewer lines. ď‚Ą Many sg iron pipes are strong and functional even after over 100 years which makes them a favourite choice. ď‚Ą They are also less prone to corrosion and damage due to their resistance to formation of linear cracks. ď‚Ą

Sg iron castings are less prone to corrosion and have a longer life span than steel. They are extremely flexible and can be easily moulded into many different forms, shapes and sizes making them a popular choice for the manufacture of pumps, valves and pipes
Specific parts of vehicles such as highway trucks, agricultural tractors which tend to damage and wear out easily are now being replaced with sg iron. The vehicular parts made of sg iron last longer and are also light weight. It is most commonly used in manufacture of compressors.
Sg iron is popular in the construction of ship propulsion units and the frames of large machines because of their durability, light weight, resistance to distortion and the ease with which they can be moulded.

In building machinery and parts used for mining and construction. SG iron is also commonly used in gear boxes, pipes, oil well frames and drilling devices used in power generation and renewable energy industry. SG iron castings is also commonly used in building gas turbines and compressors.
