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:

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 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
In welding, carbon equivalent (CE) calculations are used to predict heat affected zone (HAZ) hardenability in steels. These CE equations can be used to establish criteria to predict cold-cracking, as they can predict maximum hardness.
Pcm (Pcm =C+Si/30+(Mn+Cu+Cr)/20+Ni/60+Mo/15+V/10+5B) created by Ito and Bessyo in Japan and CEq (CEq=C+Si/25+(Mn+Cu)/16+Ni/40+Cr/10+Mo/15+V/10) devised by Düren became the public debut, where Pcm is commonly applied in modern steels containing no more than 0.11 wt% carbon typically in pipeline manufacture.
26 paź 2020 · Carbon equivalent is the key to predicting steel behavior. 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 alloying elements.
