Macrostructure and pollution B macrostructure of wire rod, are not allowed discontinuity of the metal caused by the presence of non-metallic inclusions, shrinkage porosity, shrinkage, bubbles, delaminations, cracks and voids.
Microstructure Rod must have a microstructure of ferrite + pearlite. Local podolka rod is not allowed (martensitic and toostonedtocare areas).
