ʻO ka High Strength Ductile Iron Bar kahi mea kiʻekiʻe loa i hana kūikawā ʻia no nā ʻāpana mīkini e koi ana i ka paʻakikī a me ka hiki ke hana. ʻIke ʻia hoʻi ʻo SG Iron a i ʻole Spheroidal Graphite Iron, hoʻohui kēia mea i ka maʻalahi o ka hoʻolei ʻana o ka hao me nā waiwai mechanical e kokoke ana i ke kila. Me kona ikaika kūikawā, ka machinability maikaʻi loa, a me nā hiki ke damping haʻalulu, ua lilo ka ductile iron bar i koho makemake ʻia no nā ʻano hana ʻoihana like ʻole, me nā ʻōnaehana hydraulic, nā ʻāpana mīkini, a me nā ʻāpana hoʻoili mana.
ʻAʻole e like me ka hao hina, hōʻike ka hao ductile i ka graphite i ke ʻano poepoe, kahi e hoʻonui ai i kona ikaika tensile a me ke kū'ē ʻana i ka hopena. Hāʻawi kēia pono microstructural iā ia i ke kūpaʻa kiʻekiʻe ma lalo o nā kūlana ukana kaumaha, e kūpono ai no nā ukana static a me dynamic. Loaʻa nā pā hao ductile i nā diameters like ʻole a hiki ke hoʻolako ʻia i nā kūlana ʻino a i ʻole nā mīkini kikoʻī e hoʻokō i nā koi ʻoihana like ʻole.
- hana ʻia nā kaola hao ductile e like me nā kūlana honua. Hōʻike ʻia nā ʻano kila i hoʻohana pinepine ʻia o nā kaola hao ductile ma nā ʻano like ʻole e like me nā ʻāina a me nā kūlana like ʻole.
Eia nā papa kila hao ductile i hoʻohana pinepine ʻia (nā papa) ma lalo o kekahi mau ʻōnaehana maʻamau maʻamau:

ʻO ka hao ductile kahi mea e hoʻomaikaʻi ai i kona mau waiwai mechanical ma ka hoʻohui ʻana i nā mea spheroidizing e like me ka magnesium a i ʻole cerium i ka hao i hoʻolei ʻia e hana i ka graphite i loko o kahi ʻano poepoe. Ma ke ʻano o ka hoʻohui kemika, ʻo nā ʻāpana nui o ka hao ductile he hao, kalapona, silicon, a me ka manganese, phosphorus, sulfur a me nā mea ʻē aʻe. ʻO ka hoʻohui ʻana o nā mea spheroidizing e like me ka magnesium a i ʻole cerium ke kī, kahi e paipai ai i ka hoʻokumu ʻana o kahi ʻano poepoe i loko o ka graphite.
Hoʻohana pinepine ʻia nā koʻokoʻo hao ductile i nā wahi e like me nā kia a me nā ʻāpana koʻokoʻo i ka hana mīkini, nā crankshafts a me nā koʻokoʻo hoʻohui i ka ʻoihana kaʻa, nā paipu a me nā ʻāpana kūkulu i ke kahua kūkulu, nā ʻāpana hydraulic i nā mīkini kūkulu, a me nā valves a me nā kino pamu i ka ʻoihana ikehu.
