Ibyuma bita "Stainless Steel" ni ijambo rihinnye risobanura "stainless aside". Byitwa "Stainless Steel" bifite "stainless corruption medium" idakomeye cyangwa "Stainless Steel", nk'umwuka, umwuka n'amazi. Ubwoko bw'icyuma cyangiza "chemical corruption medium" (aside, alkali, umunyu, nibindi) byitwa "stainless steel".
Dukurikije imiterere y’ikigo, gishobora kugabanywamo icyuma cya martensitic, icyuma cya ferritic, icyuma cya austenitic, icyuma cya austenite – ferrite (icyiciro 2) n’icyuma cya precipitation stainless steel. Byongeye kandi, gishobora kugabanywamo icyuma cya chromium stainless steel, icyuma cya chromium nickel stainless steel na chromium manganese stainless steel hakurikijwe ibigize.
Ijambo "icyuma kidafunze" ntirivugwa gusa ku cyuma gifunze neza ahubwo risobanura ubwoko burenga ijana bw'icyuma kidafunze. Kandi iterambere rya buri cyuma kidafunze rifite imikorere myiza mu mikoreshereze yacyo yihariye. Kubwibyo, intambwe ya mbere ni ukumenya ikoreshwa, hanyuma hagashyirwaho ubwoko bukwiye bw'icyuma hakurikijwe imiterere ya buri bwoko bw'icyuma kidafunze.
Bitewe n’uko irwanya ingese neza, ihuye neza kandi ikagira ubushobozi bwo kugenda neza mu bushyuhe bwinshi, icyuma kitagira umugese nacyo ni ibikoresho byiza cyane ku bacuruza ibifunga.
