This study presents an evaluation of two methods to measure phases in welded samples of super duplex stainless steel UNS S32750. The aim is to identify the most suitable method for characterizing the microstructure of welded joints of this steel. In the color contrast method, it was found that there was no great variation in the results due to the low value of the standard deviation. While for the ASTM E 652 standard point counting method, the percentage values of ferrite found were slightly higher than the previous method. However, these two methods produced low standard deviations and, since the method described by the standard is possible to differentiate deleterious phases, this technique is the most suitable for the microstructure characterization for welded samples of super duplex stainless steel.
