spa c carbon equivalent

Equivalent carbon content WikipediaIn 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 hydrogeninduced cold cracking, which is the most common weld defect for steel, thus it is most commonly used to determine weldability.

  • Carbon Equivalence Formula ASTM (testing materials)

    Jun 16, 2006 · There are several versions of carbon equivalent formula's that were developed specific to the families of steel – low carbon low alloy, C Mn, C Mn Si, etc. For example, the CE formula applicable to low carbon steel does contain the Si term, although this contribution has a very small effect on the total CE and subsequent preheat requirements because of the size of the denominator.
