I-iron ductile ilungele izinto ze-valve, ngoba inezinto eziningi eziwusizo.Njengengxenye yensimbi, i-ductile iron yasungulwa ngo-1949. I-carbon content yensimbi ekhonjiwe ingaphansi kuka-0.3%, kuyilapho i-cast iron ne-ductile iron okungenani i-3%.Okuqukethwe kwekhabhoni ephansi yensimbi ekhonjiwe kwenza ikhabhoni ekhona njengegraphite yamahhala ingakhi ama-flakes.Uhlobo lwemvelo lwekhabhoni ensimbi ekhonjiwe ama-graphite flakes amahhala.Ku-iron ductile, i-graphite isesimweni samaqhuqhuva esikhundleni sama-flakes njengase-iron cast.Uma kuqhathaniswa ne-cast iron ne-cast steel, i-ductile iron inezinto ezibonakalayo ezingcono.Amaqhuqhuva ayindilinga avimbela ukwakhiwa kwemifantu, ngaleyo ndlela anikeze i-ductility ethuthukisiwe enikeza ingxubevange igama layo.Kodwa-ke, i-flake ensimbi ekhonjiwe iholela ekuntulekeni kwe-ductility yensimbi.I-ductility engcono kakhulu ingatholwa yi-matrix ye-ferrite.

Uma kuqhathaniswa ne-cast iron, i-ductile iron inezinzuzo eziphelele zamandla.Amandla aqinile we-ductile iron angama-60k, kanti awe-cast iron angama-31k kuphela.Amandla okukhiqiza ensimbi eyi-ductile angama-40k, kodwa insimbi ekhonjiwe ayibonisi amandla okukhiqiza futhi izoqhekeka ekugcineni.

Amandla ensimbi eyi-ductile afana nalawo ensimbi ekhonjiwe.I-Ductile iron inamandla okukhiqiza aphezulu.Amandla okukhiqiza aphansi kakhulu e-ductile iron angama-40k, kuyilapho amandla okukhiqiza ensimbi ekhonjiwe angama-36k kuphela.Ezitshalweni eziningi zikamasipala, ezifana namanzi, amanzi anosawoti, isitimu, ukumelana nokugqwala kanye nokumelana ne-oxidation yensimbi edonsayo kuphakeme kunaleyo yensimbi ekhonjiwe.I-Ductile iron yaziwa nangokuthi i-spheroidal graphite iron.Ngenxa ye-spheroidal graphite microstructure, i-ductile iron iphakeme kune-cast steel ekudlidlizeni okudambisayo, ngakho-ke isiza kakhulu ekwehliseni ingcindezi.Isizathu esibalulekile sokukhetha insimbi eyi-ductile njengempahla ye-valve ukuthi inezindleko eziphansi kune-cast steel.Izindleko eziphansi ze-ductile iron zenza le nto idume kakhulu.Ngaphandle kwalokho, ukukhetha i-iron ductile kunganciphisa izindleko zomshini.
