S G Iron Castings (Spheroidal Graphite Iron Castings / Nodular Iron Castings) Manufacturer & Exporter of S G Iron Castings.

S G Iron is also known as Spheroidal Graphite Iron, Ductile Cast Iron, Nodular Cast Iron, Spherulitic Graphite Cast Iron. S G 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. This imparts a measurable degree of ductility (easily manipulated) to the cast metal. The ductile iron family offers the design engineer a unique combination of strength, wear resistance, fatigue resistance, and toughness, as well as excellent ductility characteristics.

S G Iron/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.

This nodular graphite structure inhibits the creation of linear cracks hence the ability to withstand distortion.

Composition :
A typical chemical analysis of this material:

  • Carbon 3.2 to 3.6%
  • Silicon 2.2 to 2.8%
  • Manganese 0.1 to 0.5%
  • Magnesium 0.03 to 0.05%
  • Phosphorus 0.005 to 0.04%
  • Sulfur 0.005 to 0.02%
  • Copper 0.40%
  • Iron balance

Other elements such as copper or tin may be added to increase tensile and yield strength while simultaneously reducing ductility. Improved corrosion resistance can be achieved by replacing 15% to 30% of the iron in the alloy with varying amounts of nickel, copper, or chromium.

Applications :
Ductile iron is specifically useful in many automotive components, where strength needs surpass that of aluminum but do not necessarily require steel. Other major industrial applications include off-highway diesel trucks, Class 8 trucks, agricultural tractors, and oil well pumps, etc.


S G Iron / Ductile Iron Chemical Components

S G Iron Ductile Iron Chemical ComponentsDuctile iron is also called as nodular iron or SG iron. Its chemical components did not have strict range for many material standards, however, its range should be useful for buyers to evaluate the quality of cast iron.

Therefore, we filled some normal standards to show the reasonable range to ductile iron. Please remember the chemical components are only a reference, not a strict standard to the material. The foundry could adjust its chemical components according to their experience in order to meet the physical properties. So, physical properties should be the only standard to materials.
