Inconel 718 Kopo

Inconel 718 e na le ts'ireletso e ntle ea ts'enyeho le khanyetso ea yang ho enjine ea jete le lits'ebetso tsa turbine ea khase. Motsoako ona o sebelisetsoa likarolo tse hlokang ho hanyetsoa hampe le khatello ea maikutlo ho fihla ho 1300 ° F (704 ° C) le khanyetso ea khase ho fihlela 1800 ° F (982 ° C). Esita le maemong a batang haholo, Inconel ea mochini 718 e na le litšobotsi tse ntlehali tsa ho tensile le ho ama. AMS 5662 e hloka matla a chai ≥ 150,000 psi mocheso oa kamore.
