Ikhabhoni (C): Umxholo wekhabhoni kwintsimbi uyanda, inqanaba lokukhupha, amandla okutsalwa kunye nobunzima buyanda, kodwa iipropati zeplastiki kunye nefuthe ziyancipha. Xa umxholo wekhabhoni udlula i-0.23%, ukusebenza kwentsimbi yokuwelda kuyawohloka, ngoko ke ukuba isetyenziselwa ukuwelda Umxholo wekhabhoni wentsimbi yokwakha ene-alloy ephantsi ngokubanzi awudluli kwi-0.20%. Umxholo ophezulu wekhabhoni uya kunciphisa ukumelana nokugqwala emoyeni kwentsimbi, kwaye intsimbi enekhabhoni ephezulu kwindawo evulekileyo kulula ukuyigqwala; ukongeza, ikhabhoni inokunyusa ukubanda kunye nobuthathaka bokwaluphala kwentsimbi.
I-Silicon (Si): I-silicon yongezwa njenge-arhente yokunciphisa kunye ne-deoxidizer kwinkqubo yokwenza intsimbi, ngoko ke intsimbi ebuleweyo ine-silicon eyi-0.15-0.30%. I-silicon inokuphucula kakhulu umda we-elastic, i-yield point kunye namandla okutsalwa kwentsimbi, ngoko ke isetyenziswa kakhulu njengentsimbi e-elastic. Ukwanda kobuninzi be-silicon kuya kunciphisa ukusebenza kwentsimbi e-welding.
IManganese (Mn)Kwinkqubo yokwenza intsimbi, i-manganese yi-deoxidizer elungileyo kunye ne-desulfurizer. Ngokubanzi, intsimbi ine-0.30-0.50% ye-manganese. I-Manganese inokunyusa amandla kunye nobunzima bentsimbi, yonyuse ukuqina kwentsimbi, iphucule ukusebenza okushushu kwentsimbi, kwaye inciphise ukusebenza kwentsimbi yokuwelda.
I-Phosphorus (P)Ngokuqhelekileyo, i-phosphorus yinto enobungozi kwintsimbi, eyonyusa ukubanda kwentsimbi, yonakalise ukusebenza kwe-welding, inciphisa i-plasticity, kwaye yonakalise ukusebenza kwe-cold going. Ke ngoko, umxholo we-phosphorus kwintsimbi kufuneka ube ngaphantsi kwe-0.045%, kwaye imfuneko yentsimbi esemgangathweni ophezulu iphantsi.
I-Sulfur (S): I-Sulfur ikwayinto enobungozi phantsi kweemeko eziqhelekileyo. Yenza intsimbi itshise ibe buthathaka, inciphise ukuqina kwentsimbi, kwaye ibangele imingxunya ngexesha lokubumba nokuqengqeleka. I-Sulfur ikwayingozi ekusebenzeni kwe-welding, inciphisa ukumelana nokugqwala. Ke ngoko, umxholo we-sulfur ngokubanzi kufuneka ube ngaphantsi kwe-0.045%, kwaye imfuneko yentsimbi esemgangathweni ophezulu iphantsi. Ukongeza i-sulfur eyi-0.08-0.20% kwintsimbi kunokuphucula ukusebenza kwayo, kwaye ngokubanzi ibizwa ngokuba yintsimbi eqhekezayo.
I-Vanadium (V)Ukongeza i-vanadium kwintsimbi kunokuphucula ulwakhiwo lwesakhelo kwaye kuphucule amandla kunye nokuqina.
I-Niobium (Nb): I-Niobium inokuyicoca iinkozo kwaye iphucule ukusebenza kwe-welding.
I-Copper (Cu): I-Copper inokuphucula amandla kunye nokuqina. Ingxaki kukuba ithambekele ekubeni buthathaka xa isetyenziswa kushushu, kwaye umxholo wobhedu kwintsimbi elahliweyo udla ngokuba phezulu.
I-Aluminiyam (Al): I-Aluminium yi-deoxidizer esetyenziswa kakhulu kwisinyithi. Inani elincinci le-aluminium longezwa kwisinyithi ukuze kucocwe iinkozo kwaye kuphuculwe ukuqina kwempembelelo.
