* Manganese zvirimo zvinogona kuwedzerwa ne 0.05% yehuwandu 0001% kuderedzwa muCarbon Zvemukati, kusvika kune yakakura ye1,65%.
* Hapana chinangwa chekuwedzera kweBoron zvinobvumidzwa, vakasara b≤0.001%
Kabhoni zvakafanana:
Cep CM: ≤0.25
Ceiiw: ≤0.43
* Shandisa CE kana iyo kabhoni yezvinyorwa yakakura kupfuura 0,12%, uye ushandise CE IIWP CM yeCarbon Zviri pasi kana yakaenzana ne 0,12%.
Cep CM = C + SI / 30 + MN / 20 + CU / 20 + Ni / 60 + CR / 20 + V / 10 + 5B
If the result of the smelting analysis of B is less than 0.0005%, then there is no need to include the analysis of element B in the product analysis, and the B content can be treated as zero in the carbon equivalent CEP cm calculation.
CEIIW = C + MN / 6 (C + Mo + V) / 5 + (ni + cu) / 15
