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:

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%)
The carbon equivalent is a measure of the tendency of the weld to form martensite on cooling and to suffer brittle fracture. When the carbon equivalent is between 0.40 and 0.60 weld preheat may be necessary. When the carbon equivalent is above 0.60, preheat is necessary, postheat may be necessary.
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.
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.
CE is Carbon Equivalent as given in AWS D1.1. Pcm formula is by Japanese Welding Engineering Society’s critical metal parameter: C.E. Weldability. 0.15 Max. Excellent Weldability with all process, No preheat, Interpass or Postheat necessary. 0.15 to 0.30.
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.
