a Including cut lengths from wire.
b Initial annealing treatment may be omitted if the conditions for previous hot working and subsequent cooling have been such that the requirements for the final mechanical properties of the product and the resistance to intergranular corrosion as defined in EN ISO 3651-2 are obtained.
c Width across flats for hexagons.
d Elongation A5 is valid only for dimensions of 5 mm and above. For smaller diameters, the minimum elongation has to be agreed upon at the time of enquiry and order.
e  In the range 1 mm ≤ d < 5 mm valid only for rounds. The mechanical properties of non round bars with thicknesses < 5 mm have to be agreed at the time of enquiry and order.
*)  1MPa = 1 N/mm².
