Inconel 718 mau hiʻohiʻona
ʻO Inconel 718 kahi superalloy e hoʻopaʻa nei i ka nickel me ka pale ʻana i ka corrosion wela kiʻekiʻe.Hoʻohana maʻamau i ka ʻoihana aerospace, hāʻawi ʻo Inconel 718 i ka ikaika mechanical kiʻekiʻe a me ka ductility maikaʻi loa a hiki i 704°C/1300F.ʻAʻole ia he magnetic ma ke ʻano.
He kūʻē maikaʻi ka superalloy 718 i hoʻokumu ʻia i ka Nickel i ka hoʻoheheʻe ʻana a me nā ʻano ʻino ʻē aʻe i loko o ka mīkini mokulele mokulele a me nā noi turbine kinoea ma ka ʻāina.ʻO ia ka mea kūpono no nā noi e koi ana i ke kūpaʻa maikaʻi loa i ka kolo a me ke koʻikoʻi o ka corrosion cracking (a hiki i 982 ° C a i ʻole 1800F).Hāʻawi ʻo Alloy 718 i ka pale piha mai ka lua a me ka crevice corrosion i nā sulfides, chlorides, carbon dioxide a me nā wahi ʻino ʻē aʻe.
ʻO Inconel 718 he mau waiwai piha maikaʻi i loko o ke ana wela o -253 a 700 °C, ʻo ka ikaika hua ma lalo o 650 °C ke kūlana mua ma nā superalloys deformed, a he maikaʻi ke kūpaʻa luhi, ka pale ʻana i ka radiation, ke kūpaʻa oxidation, ke kūpaʻa corrosion, a me ka hana maikaʻi.ʻO ka hana ʻana i ka hana, ka hana kuʻi ʻana a me ka paʻa ʻana o ka hui lōʻihi, hiki iā ia ke hana i nā ʻāpana like ʻole me nā ʻano paʻakikī, a ua hoʻohana nui ʻia i ka pae wela ma luna o ka aerospace, nuclear energy, a me nā ʻoihana ʻaila.
ʻO ka hui Inconel 718 kahi mea hoʻopaʻa paʻakikī nickel-chromium-hao i loko o ka niobium a me ka molybdenum.Loaʻa iā ia ka ikaika kiʻekiʻe, ka paʻakikī maikaʻi a me ke kūpaʻa corrosion i ke kiʻekiʻe a me ka haʻahaʻa haʻahaʻa haʻahaʻa ma lalo o 650 ℃.Hiki ke mālama ʻia kēia mokuʻāina a hoʻopaʻa ʻia paha ka ua.
1. Maʻalahi e hana
2. Ka ikaika tensile kiʻekiʻe, ka ikaika luhi, ka ikaika kolo a me ka ikaika rupture ma 700 ℃
3. 1000 ℃ kiʻekiʻe oxidation kū'ē
4. Paʻa kemika ma ka wela haʻahaʻa
5. Hana maikaʻi kuʻihao
Inconel 718 Nā papa like
GH4169, GH169 (Kina), NC19FeNb (Palani), NiCr19Fe19Nb5, Mo3 (Kelemānia), NA 51 (UK) Inconel718, UNS NO7718 (USA) NiCr19Nb5Mo3 (ISO)
ʻO Inconel718 Nā wahi noi huahana
Ma muli o kona ikaika wela kiʻekiʻe ma 700 ° C, kūpaʻa maikaʻi i ka corrosion a me ka maʻalahi o ka hana, hiki ke hoʻohana nui ʻia i nā manawa koi nui.
