With drawn bars sections of the solid state should be removed residual tensile stress by thermal or mechanical method.


Surface quality:

The surface bar should be clean, free prisoners, shells, bubbles, cracks, dents, and foreign inclusions. On the surface bars allowed the risks, small slivers, scratches, tracks changes, and other defects, if they are in control do not lead clean-up profiles beyond the permissible deviations in size. On the surface bars are allowed discoloration, traces of lubricant technology. In the fracture bars should not be foreign inclusions and voids.
