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.
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.
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 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 ...
In 1958, eighteen years after Dearden and O’Neill’s initial proposal on carbon equivalent (CE), the concept was accepted by British Standard BS2642[1]. The standard was then amended to include the following modified version of their equation: C+Si/24+Mn/6+Cr/5+Ni/13+. CE = (1) V/5+Mo/4+Cu/15.
