Fe is the basis.
According to TU 14-3R-55-2001, a technological addition of rare earth elements is possible to improve the quality of the metal. The content of residual elements is according to GOST 5632. Zirconium is introduced into steel to 0.10%, cerium to 0.080%, titanium to 0.10%, boron up to 0.0030%, and chemical analysis is not determined. The presence of up to 0.25% aluminum in steel is allowed.
