Ua hoʻokumu mua ʻia ʻo Alloy 718 no ka ʻoihana aerospace akā ua ʻike ʻia kona ikaika maikaʻi a me ka pale ʻana i ka corrosion e ka ʻoihana ʻaila a ua hoʻohana nui ʻia i kēia kahua.

ʻO Alloy 718 he nickel-chromium alloy hiki ke mālama ʻia i ka wela e hāʻawi i ka ikaika kiʻekiʻe, ke kūpaʻa ʻana i ka corrosion maikaʻi, ka maʻalahi o ka formability a hiki ke welded me ke kūpaʻa maikaʻi i ka haki ʻana o ka makahiki. Hiki ke hoʻohana ʻia ka alloy ma nā mahana a hiki i 700ºC.

ʻO Alloy 718 no ka ʻoihana ʻaila i mālama ʻia i ka wela e like me ka paʻakikī ʻaʻole i ʻoi aku ma mua o 40HRC ʻo ia ka mea i ʻae ʻia e NACE MR-01-75/ ISO 15156: 3 e pale ai i ke koʻikoʻi corrosion māwae. ʻO nā noi nui ma kēia kahua ʻo Valves a me nā paipu pololei.

ʻO Alloy 718 no ka aerospace a me ka hoʻomohala mana ua mālama ʻia ka wela e hāʻawi i ka ikaika kiʻekiʻe a me ke kūpaʻa kolo kiʻekiʻe me nā koina paʻakikī maʻamau ma mua o 42HRC. ʻO nā noi nui nā ʻāpana no nā turbines gas, nā ʻenekini mokulele, nā mea hoʻopaʻa a me nā noi ikaika kiʻekiʻe.
