Casting process simulation is used by NovaCast to develop comprehensive modelling of the intended production process to determine the size and shape of sprues, runners, gates, and risers. One of the main benefits of these systems is that they make it possible for us to quickly identify areas within the casting geometry that could give … Read more
SPHEROIDAL GRAPHITE CAST IRON 420/12
(BS EN 1563:1997)
Spheroidal Graphite Cast Iron 420/12, also known as Ductile Cast Iron, is a type of cast iron that has been treated while molten with an element such as Magnesium or Cerium to induce the formation of free Graphite as nodules or spherulites. The rounded shape of the nodules creates less stress points than the flat graphite flakes found in Grey Iron, this inhibits the creation of cracks and provides enhanced ductility. This nodular graphite structure inhibits the creation of linear cracks hence the ability to withstand distortion. In addition, Ductile Iron provides a unique combination of strength, wear resistance, fatigue resistance, and toughness. Products cast using ductile iron include valves, impellers, winch drums, separator body liners, etc.
