The carbon equivalent equations in Group I considered the metal alloying elements to be more important than carbon. These equations were considered to be more suitable for steels where the carbon level was greater than 0.16%. Examples of equations that fall into this group are CE WES and CE IIW.

    Metallurgy Matters: Carbon content, steel classifications maximum carbon equivalent

    But carbon also increases brittleness and reduces weldability because of its tendency to form martensite. This means carbon content can be both a blessing and a curse when it comes to commercial steel. And while there are steels that have up to 2 percent carbon content, they are the exception. Most steel contains less than 0.35 percent carbon.Carbon Equivalence Formula - ASTM (testing materials) Jun 16, 2006 · The carbon equivalent formulas were originally developed based on evaluating the effects of alloy addition to crack susceptibility of the base metal HAZ.
