The chemical composition of ductile iron 500 (or QT500-7) mainly includes carbon, silicon, manganese, sulfur, phosphorus and other elements, the specific content is as follows:
Carbon (C) : 3.6% to 3.8%
Silicon (Si) : 2.34% to 2.86%
Manganese (Mn) : less than 0.6%
Sulfur (S) : less than or equal to 0.025%
Phosphorus (P) : less than or equal to 0.08%
In addition, ductile iron 500 also contains magnesium and rare earth elements, the content of magnesium is 0.02% to 0.04%, and the content of rare earth is 0.03% to 0.05%. These chemical components ensure the strength and toughness of the ductile Iron 500, which is suitable for a variety of engineering applications, such as oil pump gears for internal combustion engines and medium temperature cylinder partitions for steam turbines
