The entered proportions of alloying elements result in the following carbon equivalents:

Alloying elementAbbreviationAllowed valuesPercentage [%]
CarbonC 0,05 to 0,32 %
ManganeseMn 0,50 to 1,90 %
MolybdenumMo 0,00 to 0,75 %
ChromiumCr 0,00 to 1,50 %
CopperCu 0,00 to 0,70 %
NickelNi 0,00 to 2,50 %
VanadiumV 0,00 to 0,18 %
SiliconSi 0,00 to 0,80 %
BoronB 0,000 to 0,005 %
