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%.
