Macrostructure and pollution In the fracture of cast bar billets (LPZ) on the other 14-1-3315-81 not allowed: oxide films, gas bubbles and shells, foreign non-metallic inclusions. The presence of podnasadochnogo looseness in the bars is not a rejection symptom. On the surface of rods permitted: rabiza, the color of the tint, clean the sink and Nikitiny. The quality of the bends and the surface of the bars shall conform to the standards agreed with VIAM.
