Gray and ductile iron differences. Some metallurgists will say the difference between gray and ductile iron is that ductile iron is an "upgraded" version of gray iron. It's not that simple. Continuous cast gray iron is recommended for straightwear applications in the hydraulics industry due to its lower tensile strength, higher thermal conductivity, and higher damping capacity. it's an ideal ...

Ductile iron (DI) is like cast iron, except that it has a lower percentage of carbon and has annealing and/or additives, such as magnesium, to form a different (nodular) matrix. This makes it stronger and more ductile than cast iron. Its corrosion resistance is very similar to cast iron. DI is commonly used for city water mains.
