Fe is the basis.
According to TU 14-1-3332-82, the chemical composition is given for steel 09HG2NABCH. In steel, the deviation from the normalized chemical composition by carbon is -0.020%, in aluminum ± 0.010%, and by the content of the remaining elements and residuals - according to GOST 4543. The RKM (cerium group) is introduced into the deoxidized steel at a rate of not less than 1 kg per ton and the production of cerium in the metal in an amount of 0.015-0.030%. The content of cerium is not a delivery indicator, but is controlled and entered in the certificate.
