Nodular iron | Grundfos

    The round shape of nodular graphite reduces the stress concentration and consequently, the material is much more ductile than grey iron. Nodular iron is normally used for pump parts with high strength requirements. Nodular iron contains around 0.03-0.05% by weight of magnesium.

    Measuring Nodularity in Cast Iron - olympus-ims

    Application: Measuring the degree of nodularity in cast iron, or distinguishing nodular iron from gray iron. Background: Carbon in the form of graphite is often used as an additive in the production of cast iron, amounting to 2 to 4 percent by weight or 6 to 10 percent by volume in typical castings. The microstructure of graphite within cast iron has major effects on the casting's mechanical ...

    The Difference between Cast Iron and Ductile Iron

    Prices are always an important issues for customers. Ductile iron just needs some extra nodular agent materials than grey iron, so its production costs are only some higher than cheapest grey iron, but far lower than malleable iron and austenitic iron. This is also the main reason why ductile iron is replacing malleable iron.

    Ductile iron - Wikipedia

    Ductile iron, also known as ductile cast iron, nodular cast iron, spheroidal graphite iron, spheroidal graphite cast iron and SG iron, is a type of graphite-rich cast iron discovered in 1943 by Keith Millis. While most varieties of cast iron are weak in tension and brittle, ductile iron has much more impact and fatigue resistance, due to its nodular graphite inclusions.
