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.
