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

Alloying element Abbreviation Allowed values Percentage [%]
Carbon C 0,05 to 0,32 %
Manganese Mn 0,50 to 1,90 %
Molybdenum Mo 0,00 to 0,75 %
Chromium Cr 0,00 to 1,50 %
Copper Cu 0,00 to 0,70 %
Nickel Ni 0,00 to 2,50 %
Vanadium V 0,00 to 0,18 %
Silicon Si 0,00 to 0,80 %
Boron B 0,000 to 0,005 %
Niobium Nb 0,00 to 0,06 %

The carbon equivalent is a measure of the tendency of a material to form cold cracks depending on its chemical composition. Further explanations of the individual carbon equivalents (CET, CE, PCM, CEM, CEN) can be found here.
