a) Axial： l；Tangential：tr.

① The solution treatment may be omitted if the conditions for hot working and subsequent cooling are such that the requirements for the mechanical properties of the product and the resistance to intergranular corrosion as defined in EN ISO 3651-2 are obtained.
② The tensile strength value may be raised by 200 MPa and the minimum elongation value be lowered to 20 % for bars having a final cold defonnation.
