For thicknesses ≥ 3mm; for section sizes D/T ≤ 10 (circular) and (B+H)/2T ≤ 10 (square and rectangular) the minimum elongation is reduced by 4 and the maximum tensile strength increased by 50 Mpa. For section sizes D/T > 10 to < 15 (circular) and (B+H)/2T >10 to <15 (square and rectangular) the minimum elongation is reduced by 2 and the maximum tensile strength increased by 50 Mpa. For thicknesses < 3mm values shall be agreed between the purchaser and manufacturer.
