As requested by a steel company, metallon consultants carried out a job aiming to define the origin of defects like incrustations and oxides, on the base of metallographic studies and process analysis.
The equipment employed was a stereo microscope, a light microscope, and a scanning electron microscope, using in this case observation of backscattered electrons and secondary electrons, as well as EDS analysis. With these results and the process analysis, the origin of the defects was defined.
