Fe is the basis.
According to TU 14-1-3638-83 the chemical composition is given for steel grade Sv-10Kh21N11FT (EP854). Aluminum is introduced into the metal according to the calculation in an amount of 0.25%. The steel determines the content of aluminum, nitrogen and arsenic - the results are recorded in the certificate. Allowable deviations in the chemical composition of the finished product and the presence of residual elements - in accordance with GOST 2246.
According to TU 14-1-3638-83 the chemical composition is given for steel grade Sv-10Kh21N11FT (EP854).
