| 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 AlN 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+Hy2T < 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 DIT < 15 (circular) and (B+Hy2T < 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). |
