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 Il trattamento dei sintomi di impotenza provoca trattamento per la disfunzione erettile negli uomini 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
