I-Carbon steel iyinsimbi enokuqukethwe kwekhabhoni kusuka cishe ku-0.05 kuya kumaphesenti angu-2.1 ngesisindo.
Insimbi ethambile (insimbi equkethe iphesenti elincane lekhabhoni, eqinile futhi eqinile kodwa engasheshi ukufutheka), eyaziwa nangokuthi i-plain-carbon steel kanye ne-low-carbon steel, manje iwuhlobo oluvame kakhulu lwensimbi ngoba intengo yayo iphansi ngenkathi inikeza izakhiwo ezibonakalayo ezamukelekayo ezinhlelweni eziningi.Insimbi ethambile iqukethe cishe u-0.05–0.30% wekhabhoni.Insimbi ethambile inamandla aphansi okuqina, kodwa ishibhile futhi kulula ukuyakheka;ubulukhuni bobuso bungandiswa ngokusebenzisa i-carburizing.
