Wire surface inspection

The wire surface is smooth and should not have any defects such as scratches, rust, folds, stalks and other defects that may cause harmful effects on the use of the wire, allowing the maximum depth not to exceed

The table specifies the depth of the defect. VD grade, TD grade wire shall not be fully decarburized, but allow partial decarburization of not more than d1.0%.  The maximum depth allowed for surface defects
