| Macrostructure and contamination |
The macrostructure of the steel on the other 14-1-1588-76, check on cross microtemplate taken from the supplied profile should not have shrinkage porosity, gas bubbles, cracks, inclusions, electraprobe, inversion of the crust and other defects visible to the naked eye. Permitted defects of a macrostructure: Central porosity - 1 point, point heterogeneity - 1 point; - exudation square - 1 point. On the open metal smelting allowed the increase of the score of defects allowed to 2. In the metal ESR allowed layer-by-layer crystallization and light the path to a score of 3. |
| Features of production |
Supply on the other shall be 14-1-1588-76 the metal is melted in the open arc electric furnaces, plasma arc furnaces, and also obtained by the method of electroslag remelting. |
