What are the Benefits of Ductile Iron?

 

Ductile iron castings are very strong compared to regular cast iron (gray iron). The tensile strength of cast iron is 20,000 – 60,000 psi while ductile iron starts at 60,000 psi and can go to 120,000 psi. The yield strength for ductile iron is generally 40,000 – 90,000 psi but the yield strength of cast iron is so low it is considered not measurable.

Let us put strength in a different way. We have seen gray iron parts break when they hit the ground after falling ten feet. With a ductile iron casting, you can hit the part all day long with an eight-pound sledge hammer and it is not likely to crack.

What causes the problem for gray iron is those graphite flakes which encourage fractures along the flakes, while the nodules in ductile iron work at keeping the iron together. Given the exact same scenario of the same part made from the two different metals, while the brittle gray iron wants to crack, the ductile iron wants to bend.

Ductile iron also has what is called excellent wear resistance because of the graphite in the iron. When you have something rubbing against ductile iron, the ductile iron wears away much slower than many other metals. The wear resistance is partly from the graphite structures that can act like a dry lubricant on the iron.

Ductile iron also dissipates (gets rid of) heat very well and can be machined fairly easily, though ductile iron is harder to work with than regular gray cast iron. Ductile cast iron dampens vibration and sound much better than steel would making ductile iron a good match for use on large machines.


 
 

What is the difference between Ductile Iron and Cast Iron?
Cast iron refers to all iron parts that are cast and have a high carbon content, but in normal usage, “cast iron” refers to gray iron, the cast parts with weaker iron structures containing graphite flakes. Ductile iron must specifically have the spherical graphite structure in the metal.
Regular cast iron can be cast cheaply, machined very easily, and strength can be added through heat treating. Gray iron lacks the strength and durability of ductile cast iron. Ductile iron castings are not much more expensive than gray iron castings yet if there is no need for the benefits of ductile iron you should probably stick with the gray iron castings.
      

 

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.
