I-iron-chromium-aluminium kanye ne-nickel-chromium electrothermal alloys ngokuvamile anokumelana ne-oxidation eqinile, kodwa ngenxa yokuthi isithando somlilo siqukethe amagesi ahlukahlukene, njengomoya, umkhathi we-carbon, umkhathi wesulfure, i-hydrogen, i-nitrogen emkhathini, njll. Wonke anomthelela othile.Nakuba zonke izinhlobo zama-alloys e-electrothermal ziye zabhekana nokwelashwa kwe-anti-oxidation ngaphambi kokushiya ifektri, zizodala umonakalo ezingxenyeni ngezinga elithile ezixhumanisini zokuhamba, ukuvunguza, nokufakwa, okuzonciphisa impilo yesevisi.Ukuze kunwetshwe impilo yesevisi, ikhasimende kudingeka lenze ukwelashwa kwe-pre-oxidation ngaphambi kokusetshenziswa.Indlela yokushisa i-electric heat alloy element efakiwe emoyeni owomile ukuya kuma-degree angu-100-200 ngaphansi kwezinga lokushisa elivumelekile le-alloy, ligcine lifudumele amahora angu-5-10, bese Vumela ihhavini ukuthi lipholile kancane.
