Wehewehe Pōkole:

ʻO INCONEL 718 (UNS N07718) kahi mea nickel chromium kūpaʻa i ka palaho. Hiki ke hana maʻalahi ʻia ka metala paʻakikī, a hiki i nā ʻāpana paʻakikī. ʻO kona mau ʻano wili, ʻoiai kona kūpaʻa i ka haki ʻana ma hope o ka wili ʻana, he mea kupaianaha. ʻO ka maʻalahi a me ka hoʻokele waiwai e hiki ai ke hana ʻia ka metala INCONEL 718, i hui pū ʻia me ka tensile maikaʻi, ka luhi o ka hana, a me ka ikaika haki, ua hopena i kona hoʻohana ʻia ʻana i nā ʻano hana like ʻole. ʻO nā hiʻohiʻona o kēia mau mea he mau ʻāpana no nā rockets wai, nā apo, nā casings a me nā ʻāpana metala pepa like ʻole i hana ʻia no nā mokulele a me nā mīkini turbine kinoea ma ka ʻāina, a me ka pahu wai cryogenic. Hoʻohana ʻia hoʻi no nā mea hoʻopaʻa a me nā ʻāpana mea hana.
