WebEach project shall define acceptable CEV or P CM values. Although for high strength steel code may accept CEV < 0.43, in some project specifications CEV may be limited to 0.41. In welding, equivalent carbon content (C.E) is used to understand how the different alloying elements affect hardness of the steel being welded. This is then directly related to hydrogen-induced cold cracking, which is the most common weld defect for steel, thus it is most commonly used to determine … See more 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 … See more • Lincoln Electric (1994). The Procedure Handbook of Arc Welding. Cleveland: Lincoln Electric. ISBN 99949-25-82-2. (Page 3.3-3) • Weman, Klas (2003).
