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.
Our carbon equivalent calculator is simple to use: Enter the weight percentage composition of each alloying element in their respective fields. Ensure you don't leave blanks — if any element is absent in your alloy, enter 0 in its field. The calculator will automatically determine the carbon equivalent in the following manner:
The carbon equivalent (CET) formula is convenient for analyzing Q + T steels and their cold cracking behavior. The CET equation gives information about the combined effects of different alloying elements, as compared to only carbon.
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
