| Macrostructure and contamination |
The macrostructure of the workpiece on the other 14-1-2903-80 when checking for cross etched templeto should not have shrinkage, blistering, delamination, foreign metal and slag inclusions are visible without using the magnifying devices. Allowable defects of the macrostructure shall not exceed, in points: Central porosity ≤ 1,0; - point nonuniformity ≤ 1,0; - exudation square ≤ 1,0; - layer-by-layer crystallization and the light circuit ≤ 3,0. Pollution steel non-metallic inclusions in points: - oxides of stroke (OS) ≤ 2,0; - oxides of point () ≤ 2,0; - silicates fragile (CX) ≤ 1,0; - silicates plastic (SP) ≤ 1,0; - silicates, non-deformed (SN) ≤ 2,5; sulphides (S) ≤ 1,0; - nitrides stroke (NS) ≤ 1,0; the nitrides of the point (NT) ≤ 1,0. |
| Features of production |
On the other 14-1-2903-80 billet is supplied in the annealed or tempered condition, stripped in accordance with the agreed standard. Clan or extract ratio of the workpiece must be not less than 4.5. |
