Ductile cast iron, eo hape e bitsoang nodular cast iron, spheroidal graphite cast iron kapa feela SG iron for short, emela sehlopha sa tšepe ea tšepe. Nodular cast iron e fumana nodular graphite ka phekolo ea spheroidization le inoculation, e leng ho ntlafatsa ka katleho thepa ea mochine oa tšepe ea tšepe, haholo-holo polasetiki le ho tiea, e le ho fumana matla a phahameng ho feta carbon steel.
Lisebelisoa tsa tšepe tsa ductile li na le ts'ebetso e ntle ea ho monya ho ts'oenyeha ho feta carbon steel, athe li-casting tsa carbon steel li na le cheseletso e ntle haholo. 'Me ho isa bohōleng bo itseng, li-ductile iorn castings li ka ba le litšoantšiso tse ling tsa ho roala le mafome. Kahoo ho lahla tšepe ea ductile ho ka sebelisoa bakeng sa matlo a pompo kapa lisebelisoa tsa phepelo ea metsi. Leha ho le joalo, re ntse re hloka ho etsa mehato ea ho li sireletsa hore li se ke tsa apara le ho rusa.
