ʻO Inconel 718 kahi ʻano Austenitic, ʻo ka paʻakikī paʻakikī e hoʻohua i ka "γ" i hana maikaʻi loa ia.ʻO ka palena o ka ua e hoʻohua ai i ka "δ" i mea ʻoi aku ka maikaʻi o ka plasticity i ka mālama ʻana i ka wela.
1. hiki ke hana
2.High tensile ikaika, endurance ikaika, kolo ikaika a rupture ikaika ma 700 ℃.
3.High inoxidability at1000 ℃.
4.Steady mechanical hana i ka haʻahaʻa wela.
ʻO ka ikaika wela kiʻekiʻe, ke kūpaʻa corrosion maikaʻi loa a me ka hana ma 700 ℃ mau waiwai i hoʻohana ʻia i loko o kahi ākea o nā kaiapuni koi kiʻekiʻe.Ua kūpono nā māka Inconel no ka hoʻohana ʻana i ka hana ʻana i nā ʻāpana i hoʻohana ʻia i loko o nā wahi koʻikoʻi e like me nā turbocharger rotors & seals, nā pahu kaʻa no ka puna wai hoʻoheheʻe uila, nā mea hana mahu, nā paipu no nā mea hoʻololi wela, nā pū kani kani hoʻoheheʻe a me nā pū mīkini. , nā pahu mele ʻeleʻele ma nā mokulele etc.
