a The deoxidation methods are designated as follows: FN = Rimming steel not permitted
FF = Fully killed steel containing nitrogen binding elements in amounts sufficient to bind available nitrogen (e.g. min. 0,020 % total Al, or 0,015 % soluble Al).
b It is permissible to exceed the specified values provided that for each increase of 0,001 % N the P max. content is also reduced by 0,005 %. The N content of the cast analysis, however, shall not be more than 0,012 %.
c The maximum value for nitrogen does not apply if the chemical composition shows a minimum total Al content of 0,020 % with a minimum Al/N ratio of 2:1, or if sufficient other N-binding elements are present. The N-binding elements shall be recorded in the Inspection Document.

a 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 grain structure.
b QS = quality steel. SS = special steel.
c If sufficient N-binding elements are present, the minimum total Al content does not apply.
d If the copper content is greater than 0,30 % then the nickel content shall be at least half of the copper content.
