Intangiriro
Ibyuma bitagira umuyonga ni ibyuma-binini cyane bifite ibyuma birwanya ruswa cyane kuruta ibindi byuma bitewe nuko hari chromium nyinshi iri hagati ya 4 na 30%.Ibyuma bitagira umwanda bishyirwa mubikorwa bya martensitike, ferritic na austenitis ukurikije imiterere yabyo.Muri addititon, bagize irindi tsinda rizwi kwizina ryimvura ikaze, ikaba ihuza ibyuma bya martensitike na austenitis.
Datasheet ikurikira izatanga ibisobanuro birambuye kubyiciro bya 347H ibyuma bitagira umwanda, bikaze gato kurenza icyiciro cya 304 ibyuma.
