The 4TECH company offers high carbon spring steel wires made according to EN 10270-1 standard.
Depending on the class of the wire, they are used for the production of compression, tension, torsion and shape springs, adapted to static or dynamic loads.
Spring wires are also successfully used for the production of various types of elements such as clips, clasps, clasps, etc.
Phosphated* high carbon spring steel wires.
| Grade | Standard | Tensile strength [MPa] | Diameters range [mm] | Packaging (depends on wire diam.) |
| SL | EN 10270-1 | 1060 – 1970 | 0,30 – 20,0 | coils 60 – 700 kg |
| SM | EN 10270-1 | 1020 – 2650 | 0,30 – 20,0 | coils 60 – 700 kg |
| SH | EN 10270-1 | 1160 – 2940 | 0,30 – 20,0 | coils 60 – 700 kg |
*phosphating provides good corrosion protection and reduces the coefficient of friction
