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 ).
The maximum value of 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 B-binding elements are present. The N-binding elements shall be recorded in the Inspection Document.
