Sand casting is a metal casting process characterised by using sand as the mold material. As cast irons are relatively inexpensive, very easily cast into complex shapes and readily machined, they are an important engineering and structural group of materials. The influence of alloy composition, particularly Si content, was examined with a pearlitic ductile iron (EN-GJS-500-7) and a fully ferritic ductile iron (EN-GJS-450-10). Our castings are testimonial to its superior infrastructure like Induction furnaces, Gas fired furnaces, Centrifugal casting machines, Continuous sand mixer, Heat treatment shop, well equipped. Materials that can be used with precision casting are all ferrous and none ferrous metals for eg alloy steel, sg iron. But as for the most of sg iron castings, sand casting process is most suitable production method. Corresponding author. These graphite nodules are nucleated on small inclusions during the solidification. Fortunately, you can control rust by painting, galvanizing, chrome plating or coating the iron with a sacrificial anode, which corrodes faster than the stronger metal.

This tougher material is known as Speroidal Graphite (SG) cast iron or Ductile Cast Iron (Figure S4). INVENTORY MANAGEMENT.
