a. The deoxidation method is designated as follows: 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. 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 impact  properties are verified only when Option 1.3 is specified. b. For thicknesses > 3 mm and section sizes D/T < 15 (round) and (B+H)/2T < 12,5 (square and rectangular) the minimum elongation is reduced by 2. For thicknesses £ 3 mm the minimum value for elongation is 17 %. c. For section sizes D/T<15 (circular) and (B+H)/2T<12,5 (square and rectangular) the minimum elongation is reduced by 2. d. For thicknesses < 3 mm see   9.2.2. e. For impact properties   for reduced section   test pieces see 6.7.2. f. This value corresponds to 27J at –30 °C (see EN 1993-1-1).
