The differences, even slight, can affect the physical properties of the metal. Carbon Equivalent is a calculation used to determine the carbon equivalency of an alloy metal. With the carbon equivalent number, properties of the metal such as application suitability can be determined. Knowing the carbon equivalent, or CE value, is particularly important in situations in which two pieces of metal will be welded together, such as welding two pipes together.
Environmental conditions can cause pipes to expand and contract or be moved. The weld spot can be a point of weakness, which is exacerbated if one pipe is stronger than the other. Optimally, two pipes welded together should work in conjunction as one unit. If the properties of the two pieces of metal are too dissimilar they will not act as one unit and the weld will either sheer or break. Knowing ahead of time how dissimilar the two pieces of metal are dictates if the pieces can in fact be welded together, if a joining piece is needed, or if special treatment is needed prior to welding.
If your steel has a carbon equivalent that exceeds 0. Table 5. Understanding your reinforcement goes beyond just strength. It also involves being aware of the ingredients in your steel. Calculating the carbon equivalent is simple, but it remains an important factor in creating quality reinforcement.
