RE: [MW:11402] Correct Answer need

Hi All,

 

Ans is A.

Please see the below explanation.

 

 

Because 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 to convert the percentage of alloying elements other than carbon to the equivalent carbon percentage, because the iron-carbon phases are better understood than other iron-alloy phases. Most commonly this concept is used in welding, but it is also used when heat treating and casting cast iron.

 

In welding, equivalent carbon content (CE) is used to understand how the different alloying elements affect hardness of the steel being welded. This is then directly related to cold cracking, which is the most common weld defect for steel, thus it is most commonly used to determine weldability.
