Ductile Iron Castings & Ductile Cast Iron

 

If cast iron is subject to a compressive load, these stress points are not particularly detrimental and flake graphite cast iron is excellent under compression. However, tensile loading above the natural tensile strength of the cast iron can cause rapid tensile failure as cracks propagate rapidly out from these stress points. The result of this is that cast iron has virtually no elongation, is a brittle material and is therefore limited in its use in tensile and shock loading applications. For years foundrymen and metallurgists tried to develop a new type of cast iron that would withstand bending and shock loading and would have the characteristics more of malleable cast iron but could be produced at the lower cost of grey cast iron. This resulted in the development of Ductile Cast Iron.

Ductile Iron Exhaust Manifolds

Advantages of ductile iron exhaust manifolds:
1. High tensile strength and elongation, so strong enough for tough working condition.

Gray Iron Exhaust Manifolds

 

Many types of exhaust manifolds were produced by gray cast iron. This is because of their some advantages.

Advantages of gray iron exhaust manifolds:
1. Low production costs, so low prices.
2. Less shrinkage defects, so low defective rates. Foundry’s favor.

 

The following list is showing the common gray iron material grades for exhaust manifolds.

What is in Ductile Iron? (Composition)

If you were to do a chemical analysis of ductile iron, this is what you would normally find:

Iron ~94%

Carbon 3.2 – 3.60%

Silicon 2.2 – 2.8%

Manganese 0.1 – 0.2%

Magnesium 0.03 – 0.04%

Phosphorus 0.005 – 0.04%

Sulfur 0.005 – 0.02%

Copper <= 0.40%

To improve the strength of ductile iron, additional tin or copper can be added. To improve corrosion resistance, copper, nickel, or chromium can replace anywhere from 15-30% of the iron.

 

 

 

Common Ductile Iron Grades

 

While there are many different ductile iron specifications, foundries routinely offer 3 common grades;
