Isishwankathelo seMibhobho yeIron eDuctile
Sekuyiminyaka engaphezu kwe-70 ukususela ekuvelisweni kombhobho we-iron ductile kwi-1940s. Ngamandla ayo aphezulu, ubude obuphezulu, ukuxhathisa umhlwa, ukuxhathisa ukothuka, ukwakhiwa lula kunye nezinye izinto ezininzi ezintle, umbhobho wentsimbi odityanisiweyo lolona khetho lubalaseleyo kwihlabathi lanamhlanje lokuhambisa amanzi negesi ngokukhuselekileyo. Intsimbi yentsimbi, ekwabizwa ngokuba yi-nodular iron okanye i-spheroidal graphite iron, ibonakala kubukho be-spheroidal graphite kwiziphumo zokuphosa.

Iimpawu zeMibhobho yentsimbi yeDuctile
Imibhobho yentsimbi erhuqwayo ifumaneka kuluhlu lweedayamitha ukusuka kwi-80 mm ukuya kwi-2000 mm kwaye ilungele zombini ukuhanjiswa nokuhanjiswa kwamanzi aselwayo (ngokuhambelana ne-BS EN 545) kunye nogutyulo (ngokuhambelana ne-BS EN 598). Imibhobho yentsimbi ye-Ductile ilula ukudibanisa, inokubekwa kuzo zonke iimeko zemozulu kwaye kaninzi ngaphandle kwesidingo sokubuyisela okukhethiweyo. Ukhuseleko lwalo oluphezulu kunye nokukwazi ukuhambelana nokuhamba komhlaba kwenza kube yinto efanelekileyo yokusetyenziswa kwemibhobho yoluhlu olubanzi lwezicelo.
Amabanga oMbhobho we-Iron weNsimbi esinokuNika ngawo
Le theyibhile ilandelayo ibonisa onke amabakala e-iron ductile material yelizwe ngalinye.IUkuba ungowaseMelika, ke ungakhetha 60-40-18, 65-45-12, 70-50-05 njl., ukuba ungowaseOstreliya, ungakhetha 400-12, 500-7, 600-3 njl.

Ukusetyenziswa kwe-Ductile Iron
Intsimbi yentsimbi inamandla amakhulu kunye ne-ductility kune-iron engwevu. Ezo zakhiwo zivumela ukuba zisetyenziswe ngokufanelekileyo kwiintlobo ngeentlobo zezicelo zemizi-mveliso, kubandakanywa umbhobho, amacandelo eemoto, amavili, iibhokisi zegiya, izindlu zempompo, izakhelo zoomatshini kushishino lwamandla omoya, kunye nezinye ezininzi. Ngenxa yokuba ayiqhekezi njengentsimbi engwevu, i-iron ductile ikhuselekile ukuba isetyenziswe kwizicelo zokukhusela impembelelo, njenge-bollards.
