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).

Test Requirement

Elongation, Tensile strength and yield strength; Tensile test in accordance with EN 10002-1; Impact strength; Impact test in accordance with EN 10045-1;Weldability; Chemical analysis in accordance with the methods listed in CR 10261.
