I-Inconel® 718 iyingxubevange ye-nickel-chromium eqinisa izulu ene-amandla aphezulu kanye ne-ductility enhle kufika ku-1300°F (704°C).le Alloy equkethe amanani abalulekile ensimbi, i-columbium, ne-molybdenum, kanye namanani amancane e-aluminium kanye ne-titanium.I-Nickel 718 nayo inokushisela okuhle kakhulu, ukwakheka, kanye nezakhiwo ezinhle kakhulu ze-cryogenic uma kuqhathaniswa namanye ama-alloys e-nickel aqina imvula.Ukusabela kokuqina kwemvula okuvilaphayo kwale alloy kuyivumela ukuthi ishiselwe kalula ngaphandle kokuqina noma ukuqhekeka.I-alloy 718 ayiyona i-magnetic.Igcina ukumelana nokugqwala okuhle kanye nokumelana ne-oxidation futhi isetshenziselwa izingxenye ezidinga ukumelana okuphezulu nokukhasa nokugqashuka kwengcindezi kuze kufike ku-1300°F (704°C) kanye nokumelana ne-oxidation kufika ku-1800°F (982°C).

I-Inconel 718 iyisakhiwo se-Austenitic, ukuqina kwemvula kukhiqiza u-“γ” kukwenze kwaba ukusebenza kahle komshini.Umngcele wemvula we-G ukhiqize u-“δ” ukwenze kwaba ipulasitiki engcono kakhulu ekwelapheni ukushisa.ngokumelana ngokwedlulele ekuqhekekeni kokugqwala kanye nekhono lokubhoboza kumazinga okushisa aphezulu noma endaweni yokushisa ephansi, ikakhulukazi i-inoxidability kumazinga okushisa aphezulu.
1.ukusebenza
2.Amandla okuqina aphezulu, amandla okukhuthazela, amandla okukhasa kanye namandla okuphuka ku-700 ℃.
3.I-inoxidability ephezulu ku-1000 ℃.
Ukusebenza kwe-4.Steady mechanical ekushiseni okuphansi.
Amandla okushisa aphakeme, ukumelana nokugqwala okuhle kakhulu kanye nokusebenza kahle ezindaweni ezingama-700 ℃ kukwenze kwasetshenziswa ezinhlobonhlobo zezindawo ezidingeka kakhulu.Amamaki e-Inconel akulungele ukusetshenziswa ekukhiqizeni izingxenye ezisetshenziswa ezindaweni ezinzima ezifana nama-turbocharger rotor & seal, shafts motor for electric submersible well furpu, amajeneretha esitimu, amashubhu okushintshanisa ukushisa, ama-baffles okucindezela umsindo wesibhamu kanye nezibhamu zemishini. , ama-black box recorder ezindizeni njll.
