Kūʻai ʻia ʻo Nickel Alloy 718 a me Inconel 7l8, ʻo ka alloy 718 kahi mea nickel-chromium ikaika kiʻekiʻe. Hāʻawi kēia huila paʻakikī makahiki i ke kūpaʻa ʻino a hōʻike i nā hiʻohiʻona e maʻalahi ke hana pū me nā kumu hana. ʻO nā waiwai nui ʻē aʻe o Nickel Alloy 718 a me Inconel 7l8:
- Kūleʻa hoʻomaha maikaʻi
- Hiki ke hana ʻia i loko o nā ʻāpana paʻakikī loa
- Hāʻawi i ka laulā wela ākea -423°F(-253°C) a i 1300°F(705°C)
- ʻO ka tensile koʻikoʻi, ka luhi, ka kolo, a me ka ikaika rupture
- Ua hoʻoikaika ʻia ʻo Gamma Prime
- ʻOi aku ka maikaʻi o ka pale ʻana a hiki i 1800°F(980°C)
- Loaʻa i ka annealed temper, old, cold worked, a i ʻole ka hana anu a ʻelemakule
Ma muli o kona ʻano ʻokoʻa o nā waiwai, kaulana ka alloy 718 me nā ʻoihana koʻikoʻi like ʻole a me nā noi e like me:
- Nā mea hoʻoheheʻe kinoea
- Nā pahu mālama cryogenic
- Nā ʻenekini mokulele
- ʻO nā motika rocket i hoʻohana ʻia i ka wai a me nā ʻāpana
- Nā mea paʻa a me nā ʻāpana mea kani
- Nā mea hoʻokaʻawale wahie nuklea
- Mea hana extrusion wela
- ʻO ka hoʻopaʻa ʻana i ka lua i lalo a me ka ikaika bolting
ʻO Nickel Alloy 718 a me Inconel 7l8 aia ma luna o 50% nickel a me kekahi mau mea like ʻole:
- Ni 52.5%
- Fe 18.5%
- Cr 19%
- Cb+Ta 5.13%
- Mo 3.05%
- Ti 0.9%
- Al .5%
- Co 1% ka nui
