Carbon equivalent formulae were originally developed to give a numerical value for a steel composition which would give an indication of a carbon content which would contribute to an equivalent level of hardenability for that steel.
The equivalent carbon content concept is used on ferrous materials, typically steel and cast iron, to determine various properties of the alloy when more than just carbon is used as an alloyant, which is typical. The idea is to convert the percentage of alloying elements other than carbon to the equivalent carbon percentage, because the iron ...
Use the values in the IIW formula for carbon equivalent: CE = C + Mn/6 + (Cu + Ni)/15 + (Cr + Mo + V)/5 = 0.20 + 0.90/6 + 0 = 0.35. Visit our carbon equivalent calculator to calculate the CE value using other formulae.
The carbon equivalent (Ceq) criterion is the classical approach: the effect of the alloying elements is taken into account to calculate the effective carbon composition for a particular grade. Various values of coefficients for the different elements are found in the literature ( Wolf, 1991 ).
PCM. The carbon equivalent PCM is based on Japanese results from Ito and Bessyo in 1969 [7]. It can be used for short cooling times and root welding [8]. Equation: PCM = C + Si/30 + (Mn + Cu + Cr)/20 + Mo/15 + Ni/60 + V/10 + 5*B . CEM
