Ductile cast iron imhando yesimbi yakasimba yakakandwa zvinhu zvakagadziridzwa muma1950s.Kuita kwayo kwakazara kuri pedyo nesimbi.Iyo yakavakirwa pakuita kwayo kwakanakisa iyo yakave yakabudirira kushandiswa kukanda zvimwe zvikamu zvine simba rakaoma, simba rakakwirira, kuoma uye kupfeka kuramba.Ductile iron yakakurumidza kugadzirwa kuita yakakandwa simbi zvinhu zvechipiri kune grey cast iron.Iyo inonzi "simbi panzvimbo yesimbi", inonyanya kureva ductile iron.

Ducular iron is spherical graphite kuburikidza ne spherulation uye gestation kurapwa, izvo zvinobudirira kuvandudza michina yesimbi yakakandwa, kunyanya iyo plastiki uye kuoma, kuitira kuti uwane yakakwirira simba kupfuura kabhoni simbi.

Cast iron iine kabhoni inopfuura 2.11% yesimbi kabhoni alloy, neindasitiri yenguruve iron, zvimedu zvesimbi uye ayo alloy zvinhu mushure mekunyungudika kwekushisa kwakanyanya uye kuumbwa kwekugadzira, kuwedzera kune Fe, kabhoni uye imwe simbi yakakandwa mune graphite fomu, kana kunaya kwe graphite strip ye cast iron inonzi grey cast iron kana grey cast iron, worm cast iron inonzi worm ink iron, boka resimbi yakakandwa inonzi white cast iron kana code iron, uye spherical cast iron inonzi spherical ink cast iron.

Kemikari ye ductile iron kunze kwesimbi inowanzo: carbon content 3.0 ~ 4.0%, silicon content 1.8 ~ 3.2%, manganese, phosphorus, sulfuri yakazara haipfuuri 3.0% uye chiyero chakakodzera chepasi risingawanzoitiki, magnesium nezvimwe zvinhu zvinoputika.
