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
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:
History, uses, and equations for a range of Carbon Equivalent calculations, as used to assess steel weldability, are presented.
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.
The Great Minds of Carbon Equivalent. Part lll: The Evolution of Carbon Equivalent Equations. Wesley Wang, Senior Engineer Materials Group, EWI. In welding, carbon equivalent (CE) calculations are used to predict heat affected zone (HAZ) hardenability in steels.
This is done in two steps. First the traditional use of carbon equivalent numbers to predict weldability is explored. Literature is reviewed and possible issues with welding of advanced high strength steels are identified.
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.
