I-alloy N155 yi-Nickel-Chromium-Cobalt alloy enezongezo ze-Molybdenum kunye ne-Tungsten ezisetyenziswa ngokuqhelekileyo kwiindawo ezifuna amandla aphezulu ukuya kwi-1350 ° F kunye nokumelana ne-oxidation ukuya kwi-1800 ° F.Iimpawu zayo eziphezulu zokushisa zihambelana nesimo esibonelelweyo (isisombululo esiphathwayo kwi-2150 ° F) kwaye ayixhomekeke kubunzima beminyaka.I-Multimet N155 isetyenziswa kwinani lezicelo ze-aerospace njengemibhobho yomsila kunye ne-tail cones, ii-turbine blades, i-shafts kunye ne-rotors, amacandelo e-afterburner kunye neebholithi zobushushu obuphezulu.

I-alloy N155 inokuchasana okulungileyo kwi-corrosion kwimidiya ethile phantsi kweemeko zombini ze-oxidizing kunye nokunciphisa.Xa isisombululo siphathwa ngobushushu, i-alloy N155 ialloy inokuxhathisa okufanayo kwi-nitric acid njengentsimbi engenasici.Inokumelana okungcono kunensimbi engenasici kwizisombululo ezibuthathaka ze-hydrochloric acid.Imelana nayo yonke imilinganiselo ye-sulfuric acid kwiqondo lokushisa.I-alloy inokwenziwa ngoomatshini, ifakwe kwaye ibanda-ifakwe ngeendlela eziqhelekileyo.
I-alloy inokudityaniswa ngeenkqubo ezahlukeneyo ze-arc kunye ne-resistance-welding.Le alloy iyafumaneka njenge sheet, strip, plate, wire, coated electrode, billet stock and sane and investment castings.
Ikwafumaneka kwifom ye-re-melt stock kwi-chemistry eqinisekisiweyo.Uninzi lweefom ezisetyenzisiweyo ze-n155 alloy zithunyelwa kwimeko yokulungiswa kobushushu ukuze kuqinisekiswe iipropati ezifanelekileyo.Iphepha linikwa isisombululo sobushushu-unyango lwe-2150 ° F, ixesha elixhomekeke kubukhulu becandelo, lilandelwa ngumoya opholileyo opholileyo okanye ukucima amanzi.Isitokhwe sebha kunye nepleyiti (1/4 in. kwaye inzima) ngokuqhelekileyo isisombululo sobushushu siphathwa kwi-2150 ° F elandelwa kukucima kwamanzi.
I-alloy N155 ithwaxwa kukunganyangeki kwe-oxidation ephakathi, utyekelo lobushushu obuchaphazelekileyo kwindawo yokuqhekeka ngexesha le-welding, kunye nebhendi ebanzi yokusasazeka yepropathi yoomatshini.
