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 Longitudinal values. Transverse  values are 2 % lower.

b For thicknesses < 3 mm, see  9.2.2.

c The impact properties are  verified only when Option 1.3 is specified.

d For impact properties for  reduced section test pieces see 6.6.2.

e This value corresponds to 27J at  –30 °C (see EN 1993-1-1).
