Intsimbi inokwahlulwa ibe yintsimbi ephantsi yekhabhoni, intsimbi yekhabhoni ephakathi kunye nentsimbi yekhabhoni ephezulu.Intsimbi ye-carbon ephantsi - umxholo wekhabhoni ngokuqhelekileyo ungaphantsi kwe-0.25%;i-carbon steel medium - umxholo wekhabhoni uphakathi kwe-0.25 kunye ne-0.60%;intsimbi ephezulu yekhabhoni - umxholo wekhabhoni ungaphezulu kwe-0.60%.
