Mechanical properties meet or exceed the requirements of EN 10219.
The mechanical properties for rectangular hollow sections are tested by SSAB on the longer side of the cross section.
1) The hollow sections with D/T < 15 (round) or (B + H)/2T < 12,5 (rectangular and square), the minimum value of elongation is reduced by 2.
2) Impact testing according to EN ISO 148-1 is performed on thicknesses ≥ 6mm. The specified minimum value corresponds to a full-size specimen.
