a  Solution treatment may be omitted if the conditions for hot working and subsequent cooling are such that the requirement for the mechanical properties of the product and the resistance to intergranular corrosion as defined in EN ISO 3651-2 are obtained.
b  Width across flats for hexagons.
c  Only for guidance.
d  For rods, only the tensile strength values apply.
e When tested according to EN ISO 3651-2.
f See NOTE 2 to 6.4.
*)  1MPa = 1 N/mm².
