I-alloy 718 yaqale yenzelwe imboni ye-aerospace kodwa amandla ayo amahle kakhulu nokumelana nokugqwala kwaqashelwa yimboni kawoyela futhi manje isisetshenziswa kabanzi kulo mkhakha futhi.

Ingxubevange 718 iyingxubevange ye-nickel-chromium engaphathwa ngokushisa ukuze inikeze amandla aphezulu, ukumelana nokugqwala okuhle, ukwakheka kalula futhi okungashiselwa ngokumelana okuhle nokuqhekeka kweminyaka. Ingxubevange ingasetshenziswa emazingeni okushisa afinyelela ku-700ºC.

Ingxubevange 718 yemboni kawoyela iphathwa ukushisa ngendlela yokuthi ubulukhuni bungeqi ku-40HRC okuyisilinganiso esiphezulu esivunyelwe yi-NACE MR-01-75/ ISO 15156: 3 ukuvimbela ukuqhekeka kokugqwala kwengcindezi. Izicelo ezinkulu kulo mkhakha amaValves kanye namashubhu anembile.

Ingxubevange 718 yendawo yendiza kanye nokukhiqiza amandla iphathwa ngokushisa ukuze inikeze amandla aphezulu kanye nokumelana nokukhuphuka okuphakeme ngamavelu okuqina ajwayelekile angaphezu kuka-42HRC. Izicelo ezinkulu ziyizingxenye zezinjini zegesi, izinjini zezindiza, izibophelelo nezinye izinhlelo zokusebenza zamandla aphezulu.
