Ngokusekelwe ekwakhiweni kwezinto, i-QT900-2 ibhekwa njengematerial ephezulu enezakhiwo ezihlanganisa i-bainite noma i-tempered martensite. Amapulatifomu e-ductile iron asetshenziswa kabanzi ezinhlelweni zokugaya ngenxa yokukhazimula kwawo okuphezulu, ukumelana nokugqoka okuhle, amandla aphezulu okudonsa, nokuncipha okuncane ngaphansi komthwalo. Lezi zici zenze kube yinto ethandwayo phakathi kwabakhi bamapulatifomu agaya aphezulu, amapulatifomu okucindezela, kanye nezinkundla zokuhlanganisa, amapulatifomu wokuhlola, izindawo zamalabhorethri, ama-workbench emishini, nezinye izinto ezakhiwe ngensimbi ye-cast iron.
Emkhakheni wamapulatifomu e-cast iron, i-ductile iron isebenza njengokuphuculwa kokufaka esikhundleni se-gray iron futhi iyaqhubeka nokuba enye yezinto eziyinhloko ezithathelwa indawo. Njengematerial ephezulu, i-ductile iron isetshenziswa nasekukhiqizeni izinto ezakhiwe zedolobha ezifana nezikhwama zomgwaqo nezikhwama zokuhamba kwamanzi.
Amapulatifomu e-ductile iron angakhiqizwa ukuze ahlangabezane nezidingo zezimiso zendawo, ngezilinganiso ezingezona ezisemthethweni zifika ekwenzeni kahle kwe-nanoscale nokuphuma kwesurface okuphansi njenge-Ra0.012. Iningi lamapulatifomu aphezulu okusebenza akhiwe ngensimbi ye-ductile. Izinga lokunemba elijwayelekile lifaka 000, 00, 0, 1, 2, no-3, futhi amapulatifomu okwenziwa ngokwezifiso angakhiqizwa.
Izici eziyinhloko zamapulatifomu e-ductile iron zifaka:
Ukuzinza kwesikhathi eside kokulinganisa nokumelana nokuguquguquka;
Ukumelana okuhle kakhulu nokugqoka uma kuqhathaniswa ne-gray iron, kuholela ekupheleni kwesikhathi sokusebenza;
Ukukhazimula okuphezulu kwendawo, kunciphisa ukuvuleka kokugwazwa;
Amandla angcono okucindezela nokudonsa uma kuqhathaniswa ne-gray iron, okwenza kube kufanelekile ezinhlelweni eziphakeme zomthwalo.
Noma amapuleti e-ductile iron ahilela izindleko zokukhiqiza eziphezulu futhi awakatholakali ngokuphelele, ukusebenza kwawo okuhle kakhulu kwezimali kubabeka njengokufaka esikhundleni samapulatifomu e-gray iron ezinhlelweni zemboni zanamuhla.
