  • What is Ductile Iron? - Willman Industries

    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 ...

  • The Perfect Pipe WaterWorld

    Ductile iron pipe is more flexible, stronger, and less brittle than cast iron. Therefore, it can handle shocks from impacts and vibrations better and is less susceptible to failure from freezing conditions. However, both types of iron pipe are susceptible to corrosion over time which can weaken joint connections and effectively thin a pipe wall.
