* E mafai ona fa'atuputeleina le manganese i le 0.05% mo 0.01% uma fa'aitiitiga o le kaponi, e o'o atu i le maualuga o le 1.65%.
* E leai se fa'aopoopoga fa'amoemoeina ole boron e fa'atagaina, o totoe B≤0.001%
kaponi tutusa:
CEP cm : ≤0.25
CEIIW : ≤0.43
* Fa'aaoga le CE pe a sili atu le kaponi i le 0.12%, ma fa'aaoga le CE IIW pe aP cm le kaponi e la'ititi ifo pe tutusa ma le 0.12%.
CEP cm = C+Si/30+Mn/20+Cu/20+Ni/60+Cr/20+Mo/15+V/10+5B
Afai o le taunuuga o le smelting auiliiliga o B e itiiti ifo i le 0.0005%, e leai se manaʻoga e aofia ai le auiliiliga o elemene B i le auiliiliga o oloa, ma o le B anotusi e mafai ona togafitia e pei o le zero i le carbon equivalent CEP cm fuafuaina.
CEIIW =C+Mn/6 (C+Mo+V)/5+(Ni+Cu)/ 15
