① The deoxidation method is designated as follows: GF = Fully killed steel containing nitrogen binding elements in amounts sufficient to bind the available nitrogen and having a fine grained structure.
② If sufficient N-binding elements are present, the minimum total Al content does not apply.
③ If the copper content is greater than 0,30 % then the nickel content shall be at least half of the copper content.
