| Macrostructure and pollution |
The macrostructure of bars-prescisely should not have traces of shrinkage looseness, cracks, slag inclusions that are visible without using the magnifying devices. |
| Particularities of production of goods |
Bars-pressestelle on the other 14-1-4834-90 are supplied without heat treatment. Bars with a diameter of over 100 mm are subjected to ultrasonic testing. |
