    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:

  2. CEN is given by: Yurioka [8] illustrated a good correlation between P cm and CEN for structural steels, low-alloy steels (Ni-Cr-Mo type) and carbon steels, provided the carbon content was less than 0.17 wt%. From this comparison the following relationship was derived: CEN = 2P cm - 0.092 (C ≤ 0.17%)

  3. Equation: PCM = C + Si/30 + (Mn + Cu + Cr)/20 + Mo/15 + Ni/60 + V/10 + 5*B . CEM. The carbon equivalent CEM can only be used under the very limited conditions of the short cooling time range (2 to 6 s) and the narrow validity range of the chemical composition (C: 0.02 - 0.22, Si: 0.00 - 0.50, Mn: 0.40 - 2.10, Cu: 0.00 - 0.60, Cr: 0.00 - 0.50 ...

  4. Various formulas for carbon equivalents were proposed over the years. The two most common ones are the Carbon Equivalent Value (CEV) and Carbon Equivalent Thyssen (CET). The CEV was introduced by the International Institute for Welding (IIW) in 1967 and was the standard for many years.

  5. 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.

  6. CE is Carbon Equivalent as given in AWS D1.1. Pcm formula is by Japanese Welding Engineering Society’s critical metal parameter:

  7. 1 maj 2010 · It is shown that carbon equivalent formulae are designed to measure certain mechanical performance of the steel weld metals as well as their hardness rather than microstructural content. A new formula is also proposed to predict weldability by including Ti content of the steel weld metal.
