Macrostructure and contamination In the macrostructure of the workpiece on the other 14-1-2694-79 in the state of delivery should be free of cracks, gas bubbles, subcortical bubbles, turns brown, bundles, traces of shrinkage, inclusions, visible to the naked eye. Under the control of the workpiece on the transverse microtemplate valid Central porosity, point heterogeneity and phase separation in the square no more than 1.0 points. Layer-by-layer crystallization and the square of the increased travelmasti is not a rejection symptom. In the metal tube blank, the content of nonmetallic inclusions shall not exceed the maximum score on the scale GOST 1778: sulphide - 1.0 points, oxides of point - 2.0 points, oxides and silicates stroke - 2.0 points, silicates unde - 1.0 points. In the metal tube blank and the content of the stroke of nitride and carbonitride phases of niobium should not exceed the maximum score on the scale GOST 1778 2.5 points.
