Intsimbi engatyiwayo imfutshane kwintsimbi enganyangekiyo eneasidi. Ibizwa ngokuba yiStainless Steel enesixhobo sokutya esibuthathaka okanye iStainless Steel, esifana nomoya, umphunga namanzi. Uhlobo lwentsimbi edla i-chemical corrosive medium (i-asidi, i-alkali, ityuwa, njl. njl.) ibizwa ngokuba yintsimbi ephikisana ne-asidi.
Ngokwemeko yentlangano, inokwahlulwa ibe yintsimbi ye-martensitic, insimbi ye-ferritic, i-austenitic steel, i-austenite - i-ferrite (isigaba esiphindwe kabini) insimbi engenasici kunye nemvula eqinisa insimbi engenasici. Ukongeza, inokohlulwa ibe yintsimbi ye-chromium, i-nickel ye-chromium yensimbi engenasici kunye ne-chromium manganese i-nitrogen yensimbi engenasici ngokwendawo yayo.
Igama elithi “stainless steel” alibhekiseli nje kwintsimbi esulungekileyo ecocekileyo kodwa kwiindidi ezingaphezu kwekhulu zeshishini lentsimbi engatyiwayo. Kwaye ukuphuhliswa kwensimbi nganye engenasici kunomsebenzi omhle kwizicelo zabo ezithile. Ngoko ke, isinyathelo sokuqala kukufumanisa ukusetyenziswa, kwaye emva koko unqume uhlobo oluchanekileyo lwentsimbi ngokweempawu zohlobo ngalunye lwensimbi engenasici.
Ngenxa yokumelana nokugqwesa kwayo okugqwesileyo, ukuhambelana kunye ne-ductility eyomeleleyo kuluhlu olubanzi lobushushu, intsimbi engatyiwayo ikwayeyona mathiriyeli ikrwada igqwesileyo kubaboneleli betywina.
