Carbon steel wire EN 10270-1
This is a patented cold-drawn wire. There are several classes that differ in chemical composition and, in particular, through tensile strength.
Carbon steel – EN 10270-1 classe SM
Wire for compression, tension or torsion springs subject to medium to high static stress or rare dynamic stress.
