Vermicular graphite owes its name to the worm shape of the graphite. At least 80% of the graphite must be in vermicular form, the rest in spherical form (no lamellar form!). Vermicular graphite cast iron is standardised in DIN EN 16079:2013, the grades EN-GJV-300 to EN-GJV-450 are classified according to tensile strength.
Due to cooling, this casting contains more nodular graphite in the edge area (Figs. 5-6) than in the core. The matrix is practically purely pearlitic (approx. 99% pearlite).
