Mpweya (C): Mpweya wa carbon muzitsulo umawonjezeka, zokolola, mphamvu zowonongeka ndi kuuma kumawonjezeka, koma pulasitiki ndi zotsatira zake zimachepa.Pamene mpweya wa carbon uposa 0,23%, kuwotcherera kwachitsulo kumawonongeka, kotero ngati kumagwiritsidwa ntchito powotcherera Mpweya wa carbon otsika alloy structural zitsulo nthawi zambiri sizidutsa 0.20%.Mpweya wochuluka wa carbon udzachepetsanso kukana kwa zitsulo zamlengalenga, ndipo zitsulo za carbon pabwalo lotseguka zimakhala zosavuta kuchita dzimbiri;Komanso, mpweya akhoza kuonjezera brittleness ozizira ndi kukalamba tilinazo zitsulo.
Silicon (Si): Silicon imawonjezedwa ngati wothandizira kuchepetsa ndi deoxidizer muzitsulo zopangira zitsulo, kotero chitsulo chophedwa chimakhala ndi silicon 0.15-0.30%.Silicon imatha kusintha kwambiri malire zotanuka, zokolola komanso kulimba kwachitsulo, chifukwa chake imagwiritsidwa ntchito ngati chitsulo chotanuka.Kuwonjezeka kwa kuchuluka kwa silicon kumachepetsa kuwotcherera kwachitsulo.
Manganese (Mn).Popanga zitsulo, manganese ndi deoxidizer yabwino komanso desulfurizer.Nthawi zambiri, chitsulo chili ndi 0.30-0.50% manganese.Manganese amatha kuonjezera mphamvu ndi kuuma kwa chitsulo, kuonjezera kuuma kwachitsulo, kumapangitsa kuti chitsulo chizigwira ntchito bwino, ndi kuchepetsa kuwotcherera kwachitsulo.
Phosphorous (P): Nthawi zambiri, phosphorous ndi chinthu chovulaza muzitsulo, chomwe chimawonjezera kuzizira kwachitsulo, kusokoneza ntchito yowotcherera, kumachepetsa pulasitiki, ndikuwononga magwiridwe antchito ozizira.Choncho, phosphorous zili mu zitsulo zambiri chofunika kukhala zosakwana 0.045%, ndipo chofunika zitsulo apamwamba ndi otsika.
Sulfure (S): Sulfure ndi chinthu chovulaza nthawi zonse.Pangani chitsulo chotentha kuti chikhale cholimba, chepetsani kulimba kwachitsulo ndi kulimba, ndikupangitsa ming'alu pakumanga ndi kugudubuza.Sulfure imawononganso ntchito yowotcherera, imachepetsa kukana kwa dzimbiri.Choncho, zinthu za sulfure nthawi zambiri zimafunika kukhala zosakwana 0.045%, ndipo kufunikira kwazitsulo zapamwamba ndizochepa.Kuwonjezera 0.08-0.20% sulfure ku chitsulo kungapangitse makinawo, ndipo nthawi zambiri amatchedwa chitsulo chodula.
Vanadium (V): Kuwonjezera vanadium kuchitsulo kumatha kuyeretsa njere zamapangidwe ndikuwongolera mphamvu ndi kulimba.
Niobium (Nb): Niobium imatha kuyeretsa mbewu ndikuwongolera magwiridwe antchito.
Mkuwa (Cu): Mkuwa ukhoza kupititsa patsogolo mphamvu ndi kulimba.Choyipa chake ndi chakuti chimakhala chotentha kwambiri pakugwira ntchito yotentha, ndipo zomwe zili mkuwa muzitsulo zazitsulo nthawi zambiri zimakhala zapamwamba.
Aluminium (Al): Aluminium ndi deoxidizer yomwe imagwiritsidwa ntchito kwambiri muzitsulo.Aluminiyamu pang'ono amawonjezeredwa kuchitsulo kuti ayese njere ndikuwongolera kulimba kwake.
