ʻO ka ʻauamo hao hoʻolei nodular ASTM A536 | ʻO ke koʻokoʻo hao graphite spheroidal
Hoʻolauna Huahana
ʻO ka ASTM A536 Nodular Cast Iron Bar kahi mea i hana ʻia me ka pololei no nā noi hana kiʻekiʻe i nā ʻōnaehana hydraulic a me nā kaʻa. Hana ʻia e like me ke kūlana ASTM A536 paʻa, hoʻohui kēia spheroidal graphite (SG) hao i ka ikaika o ke kila me ka castability kiʻekiʻe a me nā hiʻohiʻona dampening haʻalulu o ka hao. He mea waiwai nui ia no kona kūpaʻa maikaʻi loa i ka luhi, ka mīkini, a me ke kūpaʻa dimensional ma lalo o ke kaomi.
ʻOkoʻa ka hao hoʻolei nodular, i kapa ʻia hoʻi he hao ductile, mai ka hao hina ma ke ʻano he mau nodules graphite spheroidal ka nui o ke kalapona ma kahi o nā flakes. Hāʻawi kēia ʻokoʻa kūkulu iā ia i ka ikaika tensile a me ka yield kiʻekiʻe, e lilo ia i mea hilinaʻi no nā wahi e halihali ana i ka ukana a me ke kaumaha kiʻekiʻe.
- 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:

Wehewehe Huahana
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.
