INCONEL® huila 718 UNS N07718/W.Nr. 2.4668

ʻO ka wehewehe pōkole:

ʻO INCONEL 718 (UNS N07718) kahi mea nickel chromium kūpaʻa kiʻekiʻe. Hiki ke hana ma'alahi ka 'au'au pa'akikī makahiki. i loko o nā ʻāpana paʻakikī. ʻO kāna mau hiʻohiʻona wili. ʻoi aku ka maikaʻi o kona kūpaʻa ʻana i ka haki ʻana o ka weld. ʻO ka maʻalahi a me ka hoʻokele waiwai me ka INCONEL alloy 718 hiki ke hana ʻia, i hui pū ʻia me ka tensile maikaʻi, ke kolo luhi, a me ka ikaika rupture, ua hopena i kona hoʻohana ʻana i kahi ākea o nā noi. ʻO nā laʻana o kēia mau ʻāpana no nā rockets i hoʻoheheʻe ʻia i ka wai, nā apo, nā pahu a me nā ʻāpana metala like ʻole i hana ʻia no nā mokulele a me nā ʻenekini turbine kinoea ma ka ʻāina, a me ka pahu cryogenic. Hoʻohana ʻia ia no nā mea paʻa a me nā ʻāpana mea kani.
