Wires, which are usually used in the cold drawn condition produced from patented wire rod (EN 10052).

The  application depends on the character of the stress.
(S)        = static load
(D)        = dynamic load and small winding ratio

With regards to the level of  stress the wires are classified in 3 tensile classes:
low, medium und high.

tensile low tensile middle tensile high tensile

static SL SM SH

dynamic DM DH

Size range
