Iron-chromium-aluminiyam kunye ne-nickel-chromium electrothermal alloys ngokubanzi zinokumelana ne-oxidation eyomeleleyo, kodwa ngenxa yokuba iziko liqulethe iigesi ezahlukeneyo, ezifana nomoya, umoya we-carbon, umoya wesulfure, i-hydrogen, i-nitrogen emoyeni, njl. Zonke zinempembelelo ethile.Nangona zonke iintlobo zee-alloys ze-electrothermal ziye zaphantsi konyango oluchasene ne-oxidation ngaphambi kokuba zihambe kwi-factory, ziya kubangela umonakalo kumacandelo kwinqanaba elithile kwiikhonkco zokuhamba, ukuvunguza kunye nokufakwa, okuya kunciphisa ubomi benkonzo.Ukwandisa ubomi benkonzo, umthengi kufuneka aqhube unyango lwangaphambili lwe-oxidation ngaphambi kokusetyenziswa.Indlela yokutshisa i-alloy yombane efakwe kwi-alloy efakwe kumoya owomileyo ukuya kuma-degrees angama-100-200 ngaphantsi kobushushu obuvumelekileyo be-alloy, yigcine ishushu kwiiyure ezingama-5-10, kwaye emva koko Vumela i-oven ukuba iphole kancinci.
