ʻO ka hao hoʻoheheʻe, ʻike ʻia hoʻi ʻo ductile cast iron, nodular cast iron, spherical graphite iron, spherical graphite cast iron a me SG iron, he ʻano o ka graphite-rich cast iron i ʻike ʻia ma 1943 e Keith Millis.ʻOiai ʻo ka hapa nui o nā ʻano o ka hao hoʻolei ʻia he nāwaliwali i ka haʻalulu a palupalu, ʻoi aku ka hopena o ka hao ductile a me ke kūpaʻa luhi, ma muli o kāna mau nodular graphite inclusions.ʻAʻole ʻo Ductile iron he mea hoʻokahi akā he ʻāpana o kahi pūʻulu o nā mea hiki ke hana ʻia me nā ʻano waiwai like ʻole ma o ka mālama ʻana i kā lākou microstructure.ʻO ka hiʻohiʻona maʻamau o kēia pūʻulu mea ʻo ke ʻano o ka graphite.I loko o nā hao ductile, aia ka graphite ma ke ʻano o nā nodules ma mua o nā flakes e like me ka hao hina.ʻOiai ʻo nā ʻōpala graphite ʻoi e hana i nā wahi koʻikoʻi i loko o ka matrix metala, nā nodules poepoe e keʻakeʻa ai i ka hana ʻana o nā māwae, no laila e hāʻawi ai i ka ductility i hoʻonui ʻia e hāʻawi i ka inoa o ka alloy.
Ua ʻike ʻia ʻo Austempered ductile iron (ADI; ʻo ia hoʻi, austenite tempered [7]) i ka makahiki 1950 akā ua kūʻai ʻia a loaʻa ka kūleʻa i kekahi mau makahiki ma hope.Ma ADI, hoʻohana ʻia ke ʻano metala ma o ke kaʻina hana wela.

ʻO ka hakina nui (%) no nā hoʻolei hao ductile ferritic[8]
He liʻiliʻi ka sulfur i loko o nā haku hao ductile ʻē aʻe.
Kalapona, 3.2–3.60%
Silika, 2.2–2.8%
Manganese, 0.1–0.2%

Hiki ke hoʻohui ʻia nā mea e like me ke keleawe a i ʻole ka tin i mea e hoʻonui ai i ka tensile a hāʻawi i ka ikaika i ka manawa like e hōʻemi ana i ka ductility.Hiki ke ho'okō 'ia ka ho'oikaika 'ana i ka corrosion ma o ka ho'ololi 'ana i ka 15-30% o ka hao i loko o ka hao me ka nui like 'ole o ka nickel, copper, a chromium.
Hiki ke hoʻololi ʻia ʻo Silicon ma ke ʻano he graphite formation element e ka alumini e hāʻawi i ka pale oxidation ʻoi aku ka maikaʻi.[9]
HONGDA Ductile hao hoolei:
I ka hoʻomaka ʻana o 2021, kūkulu ʻo HONGDA i kahi hale hana hou e hoʻolauna i nā lako hana a me ka laina hana no ka hoʻolei ʻana i ka hao Ductile.
