| Macrostructure and contamination | Macrostructure of steel to transverse the etched templeto should not be visible without using the magnifying devices of the traces of shrinkage, bubbles, cracking, slag inclusions. evaluation of the macrostructure produced by: point heterogeneity, Central porosity, phase separation and to the square of spotted segregation. Evaluation of contamination of metal non-metallic inclusions produced by: stroke oxides, oxides point, silicates fragile, silicates plastic, non-deformable silicates, sulphides. The actual results of the evaluation of macrostructure and contamination shall be recorded in the certificate. |
