What is in Ductile Iron? (Composition)
If you were to do a chemical analysis of ductile iron, this is what you would normally find:
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;
|Physical and Mechanical Properties||ASTM A536, Grade 60-40-18||ASTM A536, Grade 65-45-12||ASTM A536, Grade 80-55-06|

Ductile Cast Iron Castings
Ductile iron, a synthetic metal material that was invented in the middle of the twentieth century, is one type of iron used to make cast iron. The cast iron process involves melting down the iron and metal materials that make it ductile.
The ductile iron process must begin with the production of ductile iron, created by adding minute amounts of other elements to the iron, causing carbon to form in the shape of spheroids instead of flakes. This is what makes the material able to alter without breaking. In general, ductile iron has a higher tensile strength than grey iron, the kind of iron traditionally used to make cast iron products. Ductile iron, as its name suggests, is more ductile than traditional iron materials, which tend to be more brittle and prone to fracture under high tensile stress. Ductile iron is commonly used to make cast iron pipes, like those used in water and sewer lines. Ductile iron is used for a variety of applications in many different industries. These industries include, but are not limited to agriculture, automotive, irrigation, ventilation, hydraulics, and manufacturing.
