    4 History of Ductile Iron

    Grey iron is being produced since hundreds of years. In 1948, a major event occured when a small amount of magnesium was added to molten cast iron.

    It was found that the flaky graphite converted to spheroidal shape and accordingly all mechanical properties changed. The material with these new properties was called ductile iron.

    Advantages of ductile iron pipes

    • High tensile strength, good elastic module and excellent ductility, making it suitable for high

    stress applications and where pressure surge may be experienced.

    • High corrosion resistance.

    • Excellent hydraulic flow.

    • High working pressure compared to other types of pipes.

    • Ease of installation.

    • Long lifetime.

    • Can accommodate ground movement.

    In the previously used Grey Iron the carbon was present in
