Intsimbi engenastainless iqulethe ubuncinane be-10.5% yechromium, eyenza umaleko obhityileyo, ongabonakaliyo, kunye noncamathela kakhulu kumphezulu wentsimbi obizwa ngokuba "yi-passive layer". Lo maleko wokwenziwa yinto eyenza intsimbi engatyiwayo imelane kakhulu nomhlwa kunye nomhlwa.
Xa intsimbi isesichengeni seoksijini kunye nokufuma, ichromium esentsimbini idibana neoksijini esemoyeni ukuze yenze umaleko obhityileyo wechromium oxide kumphezulu wentsimbi. Olu maleko lwechromium oxide lukhusela kakhulu, njengoko luzinzile kwaye aluqhekeki lula. Ngenxa yoko, ikhusela ngokufanelekileyo intsimbi engaphantsi kwayo ukuba idibane nomoya kunye nomswakama, oyimfuneko ukuba inkqubo yokurusa yenzeke.
Umaleko we-passive ubaluleke kakhulu kwi-corrosion resistance of steel stainless, kwaye inani le-chromium kwintsimbi limisela amandla ayo okuxhathisa i-rust kunye ne-corrosion. Umxholo wechromium ophezulu ukhokelela kumaleko okhuselayo kunye nokumelana nokukhula okungcono. Ukongeza, ezinye izinto ezifana ne-nickel, i-molybdenum, kunye ne-nitrogen nazo zinokongezwa kwintsimbi ukuphucula ukuxhathisa ukubola.
