| Macrostructure and pollution |
In the macrostructure of wire rod, are not allowed discontinuity of the metal caused by the presence of shrinkage, axial looseness, bubbles, cracks, delamination and inclusions. |
| Microstructure |
Wire rod microstructure should be uniform. Padalka (martensitic and toostonedtocare areas) is not allowed. |
