The value |
| Macrostructure and contamination |
The fracture of steel bars on the other 14-1-2607-78 controlled on the bars with diameter 3.0 mm and above shall be homogeneous and fine-grained. The break should be free of voids, supernote, delaminations, cracks, bubbles and inclusions visible to the naked eye. Decarbonisation on the bars is not allowed. |
| Microstructure |
Microstructure of steel on the other 14-1-2607-78 should consist of uniformly distributed fine pearlite and must comply with points 1-4 of the scale GOST 801. |
| Features of production |
Bars on the other 14-1-2607-78 supplied in cold-worked condition. |
