Ingxubevange N155 ingxubevange ye-Nickel-Chromium-Cobalt enezengezo ze-Molybdenum ne-Tungsten esetshenziswa ngokuvamile ezingxenyeni ezidinga amandla aphezulu afika ku-1350°F kanye nokumelana ne-oxidation kufika ku-1800°F.Izici zayo zezinga lokushisa eliphezulu zingokwemvelo esimweni esihlinzekwayo (isixazululo esiphathwa ngo-2150°F) futhi asincikile ekuqinisweni kweminyaka.I-Multimet N155 isetshenziswa kuzinhlelo zokusebenza eziningi ze-aerospace njengamapayipi omsila nezigaxa zomsila, ama-turbine blades, ama-shafts nama-rotor, izingxenye ze-afterburner namabhawodi ashisa kakhulu.

Ingxubevange N155 inokumelana okuhle nokugqwala emithonjeni ethile yezindaba ngaphansi kokubili kwezimo ze-oxidizing nokunciphisa.Lapho isixazululo selashwa ukushisa, ingxubevange engu-N155 inokumelana okufanayo ne-nitric acid njengensimbi engagqwali.Inokumelana kangcono kunensimbi engagqwali ezixazululweni ezibuthakathaka ze-hydrochloric acid.Imelana nakho konke ukugxila kwe-sulfuric acid ekamelweni lokushisa.Ingxubevange ingenziwa ngomshini, yenziwe ngomkhonyovu futhi yakhiwe ngezindlela ezijwayelekile.
I-alloy ingashiswa ngezinqubo ezihlukahlukene ze-arc kanye ne-resistance-welding.Le alloy itholakala njengeshidi, i-strip, ipuleti, izintambo, ama-electrode ahlanganisiwe, isitokwe se-billet kanye ne-sane and investment castings.
Iyatholakala futhi ngendlela yokuncibilika kabusha kwesitoko kukhemistri eqinisekisiwe.Izinhlobo eziningi ezisetshenzisiwe ze-n155 alloy zithunyelwa esimweni esiphethwe ukushisa ukuze kuqinisekiswe izakhiwo ezinhle.Ishidi linikezwa isixazululo sokwelashwa kokushisa okungu-2150°F, isikhathi sincike ekugqileni kwesigaba, okulandelwa ukupholisa komoya okusheshayo noma ukucisha amanzi.Isitoko sebha nepuleti (1/4 in. futhi esindayo) ngokuvamile ukushisa kwesixazululo okuphathwa ngo-2150°F okulandelwa ukucisha kwamanzi.
I-alloy N155 ihlaselwe ukumelana ne-oxidation emaphakathi, ukuthambekela kokuqhekeka kwendawo ethintekile ngesikhathi sokushisela, kanye nebhande lokuhlakazeka elibanzi lezakhiwo zemishini.
