Inconel 718 jẹ alloy nickel-chromium-molybdenum ti a ṣe apẹrẹ lati koju ọpọlọpọ awọn agbegbe ti o ni ipata pupọ, pitting ati ipata crevice. Nickel, irin alloy yii tun ṣafihan ikore giga ti iyasọtọ, fifẹ, ati awọn ohun-ini rupture ti nrakò ni awọn iwọn otutu giga. Nickel alloy yii ni a lo lati awọn iwọn otutu cryogenic titi di iṣẹ igba pipẹ ni 1200 ° F. Ọkan ninu awọn ẹya iyatọ ti Inconel 718's tiwqn ni afikun ti niobium lati gba agbara lile ọjọ-ori laaye eyiti ngbanilaaye annealing ati alurinmorin laisi lile lẹẹkọkan lakoko alapapo ati itutu agbaiye. . Afikun ti niobium n ṣiṣẹ pẹlu molybdenum lati mu matrix alloy le ati pese agbara giga laisi itọju igbona ti o lagbara. Miiran gbajumo nickel-chromium alloys ti wa ni ori lile nipasẹ awọn afikun ti aluminiomu ati titanium. Nickel irin alloy yii jẹ iṣelọpọ ni imurasilẹ ati pe o le ṣe alurinmorin ni boya annealed tabi ojoriro (ọjọ ori) ipo lile. Superalloy yii ni a lo ni ọpọlọpọ awọn ile-iṣẹ bii aaye afẹfẹ, ṣiṣe kemikali, imọ-ẹrọ oju omi, ohun elo iṣakoso-idoti, ati awọn olupilẹṣẹ iparun.
Awọn paati iwọn otutu ti o ga, gẹgẹbi awọn abẹfẹlẹ turbine, awọn ayokele itọsọna, awọn disiki turbine, awọn disiki compressor titẹ giga, iṣelọpọ ẹrọ ati awọn iyẹwu ijona ti a lo ninu iṣelọpọ ọkọ ofurufu, ọkọ oju omi ati awọn turbines gaasi ile-iṣẹ.
