Ikhabhoni (C): Isiqulatho sekhabhoni ekwenyukeni kwentsimbi, inqaku lesivuno, ukomelela kokuqina kunye nokuqina, kodwa iplastiki kunye neempawu zempembelelo ziyancipha.Xa umxholo wekhabhoni udlula i-0.23%, ukusebenza kwe-welding yensimbi kuyancipha, ngoko ke ukuba isetyenziselwa i-welding Umxholo wekhabhoni we-low-alloy structural steel ngokuqhelekileyo awudluli i-0.20%.Umxholo wekhabhoni ophezulu uya kunciphisa ukuxhathisa kwe-atmospheric corrosion of steel, kunye ne-high-carbon steel kwi-stock yard evulekileyo kulula ukugqwala;Ukongeza, ikhabhoni inokonyusa i-brittleness ebandayo kunye nobuntununtunu bentsimbi.
Isilicon (Si): I-Silicon yongezwa njenge-agent yokunciphisa kunye ne-deoxidizer kwinkqubo yokwenza i-steelmaking, ngoko insimbi ebuleweyo iqukethe i-silicon ye-0.15-0.30%.I-silicon inokuphucula kakhulu umda we-elastic, indawo yesivuno kunye nokuqina kokuqina kwentsimbi, ngoko ke isetyenziswa ngokubanzi njengentsimbi ye-elastic.Ukunyuka kwexabiso le-silicon kuya kunciphisa ukusebenza kwe-welding yentsimbi.
IManganese (Mn).Kwinkqubo yokwenza isinyithi, i-manganese yi-deoxidizer efanelekileyo kunye ne-desulfurizer.Ngokuqhelekileyo, insimbi iqulethe i-0.30-0.50% ye-manganese.I-Manganese inokunyusa amandla kunye nokuqina kwentsimbi, ikhulise ukuqina kwentsimbi, iphucule ukusebenza okushushu kwentsimbi, kunye nokunciphisa ukusebenza kwentsimbi.
Phosphorus (P): Ngokubanzi, i-phosphorus yinto eyingozi kwintsimbi, eyandisa i-brittleness ebandayo yentsimbi, iphazamisa ukusebenza kwe-welding, inciphisa iplastiki, kwaye iphazamise ukusebenza kokugoba okubandayo.Ngoko ke, umxholo we-phosphorus kwintsimbi ngokuqhelekileyo kufuneka ube ngaphantsi kwe-0.045%, kwaye imfuno yensimbi ephezulu iphantsi.
Isulfure (S): Isulfure nayo iyinto eyingozi phantsi kweemeko eziqhelekileyo.Yenza intsimbi ishushu ibe brittle, ukunciphisa intsimbi ductility kunye nokuqina, kwaye kubangele iintanda ngexesha forging and rolling.Isulfure nayo iyingozi ekusebenzeni kwe-welding, inciphisa ukuxhathisa ukubola.Ngoko ke, umxholo wesulfure ufunwa ngokubanzi ukuba ube ngaphantsi kwe-0.045%, kwaye imfuno yensimbi ephezulu iphantsi.Ukongeza i-0.08-0.20% sulfure kwintsimbi inokuphucula i-machinability, kwaye ngokuqhelekileyo ibizwa ngokuba yintsimbi yokusika mahhala.
Vanadium (V): Ukongeza i-vanadium kwintsimbi kunokuphucula iingqolowa zesakhiwo kunye nokuphucula amandla kunye nokuqina.
I-Niobium (Nb): I-Niobium inokucokisa iinkozo kunye nokuphucula ukusebenza kwe-welding.
Ubhedu (Cu): Ubhedu lunokuphucula amandla kunye nokuqina.Ukungalungi kukuba kuxhomekeke kwi-brittleness eshushu ngexesha lokusebenza okushushu, kwaye umxholo wobhedu kwintsimbi ye-scrap uhlala uphezulu.
iAluminiyam (Al): I-Aluminiyam i-deoxidizer esetyenziswa ngokuqhelekileyo kwintsimbi.Inani elincinci le-aluminium lifakwe kwintsimbi yokucoca iinkozo kunye nokuphucula ukuqina kwempembelelo.
