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.
