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.
