Ibyuma bisanzwe bya karubone, bizwi kandi nk'icyuma cya karubone, bigabanyijemo ibyuma bike bya karubone (byitwa ibyuma bikozwe mu cyuma), ibyuma bya karubone buciriritse hamwe n'ibyuma bikurikije ibirimo karubone.Mubisanzwe, abafite karubone iri munsi ya 0.2% bita ibyuma bya karubone nkeya, bikunze kwitwa ibyuma bikozwe cyangwa ibyuma byera;Ibyuma birimo 0.2-1.7%;Icyuma cy'ingurube kirimo ibice birenga 1.7% byitwa ingurube.
Ibyuma bitagira umuyonga nicyuma kirimo chromium irenga 12,5% kandi irwanya cyane imiti yo hanze (aside, alkali n'umunyu).Ukurikije microstructure iri mubyuma, ibyuma bidafite ingese birashobora kugabanywa muri martensite, ferrite, austenite, ferrite austenite hamwe nimvura ikomera ibyuma bitagira umwanda.Ukurikije ibiteganijwe mu rwego rwigihugu gb3280-92, hari ingingo 55 zose hamwe.
