Ductile cast iron, eo hape e bitsoang nodular cast iron, spheriodal 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.
