1)The maximum HB values may be raised by 100 units or the maximum tensile strength value may be raised by 200 N/mm2 and the minimum elongation value be lowered to 20% for sections and bars of < 35 mm thickness having a final cold deformation.
2) For guidance only.
3)For rods, only the tensile strength values apply. |
