Fe is the basis.
According to TU 14-1-4054-85 the chemical composition is given for steel grade Sv-07HGSN3MD-Sh. The content of titanium and zirconium is calculated. The nitrogen content in the rod must not be more than 0.015%. It is allowed to supply wire with a deviation from the norms of chemical composition in accordance with paragraph 3.5. GOST 2246, subject to other requirements of the Specification.
According to TU 14-1-2203-77 the chemical composition is given for the welding wire of the brand Sv-07HGSN3MD. The content of titanium is calculated. Zirconium is introduced into the steel by 0.050%. In the steel, the determination of nitrogen and colored impurities - arsenic, lead, antimony and tin - is performed. The results of the control are optional.
