Izinto eziphathekayo ze-carbon steel plate yintsimbi ye-carbon steel okanye i-carbon steel, eyintsimbi enomxholo wekhabhoni ongaphantsi kwe-2.11% kwaye akukho zixhobo zetsimbi ezongeziweyo ngenjongo.Ukongeza kwikhabhoni, iqulethe isixa esincinci sesulfure, i-silicon, i-phosphorus, i-manganese kunye nezinye izinto.Iipleyiti zensimbi zeCarbon zinokwahlulwa zibe yikhabhoni ephantsi, ikhabhoni ephakathi kunye nekhabhoni ephezulu ngokuhambelana nomxholo wekhabhoni;ngokuhambelana nesicelo, zinokwahlulwa zibe zizixhobo, izakhiwo, kunye nentsimbi yesakhiwo ngokukhululekileyo;ngokwendlela ye-deoxidation, zinokwahlulwa zibe yintsimbi ebilayo, intsimbi efileyo, intsimbi ebuleweyo, kunye nentsimbi ekhethekileyo ebuleweyo;Ngokwendlela yokunyibilikisa, inokwahlulwa ibe yintsimbi yokuguqula, intsimbi evulekileyo yeziko lomlilo kunye nentsimbi yesithando somlilo.Ibanga leCarbon libandakanyiwe ikakhulu Q195, Q215, Q235, Q255, Q275 njl.
