Ductile Iron, also called nodular cast iron, ductile cast iron, SG Iron and spheroidal graphite cast iron is a cast iron type that is widely used for its weariness resistance, crash, scratch resistance, and elongation owing to its unique round graphite structures present in the metal.  Ductile iron is characterised by versatility and high performance at affordable costs. Here are some of the things that you must be looking in order to get the best ductile iron castings:

Mechanical properties:
We, at VR Foundries, offer ducting castings with varying mechanical characteristics. The tensile strength of ductile iron varies in the range between 60,000 to 100,000 psi with the yield of it a minimum of 40,000 psi. Ideally, it should show 18% to 30% elongation on a test casting piece.

Highly economical:
In several cases, it is found that ductile iron is better than steel, low steel and carbon in terms of affordability and superior to steel when it comes to performance. It is also comparatively fragile compared to most iron types. It is significantly less expensive compared to cast steel and bit expensive than gray iron.  We, as one of the leading producers of ductile iron castings, are aware of the wide range of heating treatments for ductile iron and how it responds to different heat treatment methods available.

Can outperform gray iron and cast steel in several applications:
If you compare the resistance power of grey iron with ductile iron, the latter fares better. Ductile iron also has greater mechanical strength and its high resistance acts against thermal shocks and physical or mechanical breakage. The scrap resistance of Ductile Iron is more often compared to the likes of steel and considered better than grey iron when there is heavy impact or heavy load. When subjected to heat treatment, the design ductility of ductile iron can be improved to a considerable degree.
