According to TU 14-1-2203-77, the chemical composition is given for the welding wire brand Sv-03GHN3MD. In the steel, an increased content of phosphorus is allowed to be 0.0050%. Cerium is introduced by calculation at 0.10% and is not determined by chemical analysis. In steel, the determination of nitrogen and colored impurities - arsenic, lead, antimony and tin - is carried out. The allowable variation in silicon content is ± 0.020%.

Macrostructure and pollution In the macrostructure of wire rod, are not allowed discontinuity of the metal caused by the presence of shrinkage, axial looseness, bubbles, cracks, delamination and inclusions.
Microstructure Wire rod microstructure should be uniform. Padalka (martensitic and toostonedtocare areas) is not allowed.
