* 1 va 6-sinflar uchun har bir 0,01% C ning pasayishi 0,30% dan past bo'lsa, 0,05% Mn ning 1,06% dan oshishiga maksimal darajaga qadar ruxsat beriladi. 1,35%.
* 6-sinf uchun kolumbium uchun limit issiqlik tahlili bo'yicha 0,05% gacha va mahsulot tahlilida 0,06% gacha oshirilishi mumkin.
* Odatda uglerod ekvivalenti CE = [C + Mn / 6 + (Cr + Mo + V) / 5 + (Ni + Cu) / 15] issiqlik tahlili bilan 0,43% dan oshmasligi kerak.
