* Hiki ke hoʻonui ʻia ka nui o ka manganese ma 0.05% no kēlā me kēia 0.01% hōʻemi ʻana i ka nui o ke kalapona, a hiki i ka 1.65%.
* ʻAʻole ʻae ʻia ka hoʻohui ʻana o ka boron i manaʻo ʻia, koena B≤0.001%
Kalapona like:
CEP kenimika: ≤0.25
CEIIW: ≤0.43
* E hoʻohana i ka CE ke ʻoi aku ka nui o ke kalapona ma mua o 0.12%, a e hoʻohana i ka CE IIW ke emi a like paha ka nui o ke kalapona ma mua o 0.12% ma P cm.
CEP cm = C+Si/30+Mn/20+Cu/20+Ni/60+Cr/20+Mo/15+V/10+5B
Inā emi ka hopena o ka loiloi hoʻoheheʻe ʻana o B ma mua o 0.0005%, a laila ʻaʻohe pono e hoʻokomo i ka loiloi o ka element B i ka loiloi huahana, a hiki ke mālama ʻia ka ʻike B ma ke ʻano he zero i ka helu ʻana o ke kalapona like CEP cm.
CEIIW =C+Mn/6 (C+Mo+V)/5+(Ni+Cu)/ 15
