| Macrostructure and contamination |
The macrostructure of the steel on the other 14-1-1396-75 on cross etched templeto should not be visible without using the magnifying devices of the traces of shrinkage, bubbles, cracks, and slag inclusions. The permissible defects of the macrostructure scores in the scales GOST 10243 shall not exceed at the point of heterogeneity, Central porosity and phase separation the square of the 2nd score; intergranular cracks - 3 points. |
