TENSILE GRADES

The tensile grades of wires are:
-1570 N/mm² for wires of all qualities.
-1770 N/mm² for bright wires quality B.
1960 N/mm² for bright wires quality B.  These nominal values are the lower limits of strength.
The upper limits are equal to the lower limits in addition to the tolerance specified in table 2.
