Wire rods used for TD and VD, with few impurities present
Oil tempered steel wire is achieved by heating the workpiece to a high temperature and then cooling it in an oil bath. This hardens the material and improves its resistance to deformation and abrasion. At VINCO we have available a wide range of chemical compositions of quenched and tempered steel wire based on the EN 10270-2 standard which applies to quenched and tempered spring steel wires.
In the mechanical characteristics section of the product data sheet you can find out what each type of hardened steel wire is used for, as well as the tensile strength of all of them. The inner and outer diameter measurements and the weight of the coil according to the nominal value in millimetres are also detailed.
The following table details the different packaging options according to the maximum weight that we offer you:
Type of packaginge | Maximum weight in kg |
Roll | 500 |
Sling Bar / Carrier | 2000 |
Coil Z | 800 |
Metallic reel DIN 560 G200/32 | 150 |
Metallic reel G200/40 | 150 |
Metallic reel G240/40 | 300 |
Wooden reel G240/40 | 300 |

In addition to these types of packaging, in the supply of oil-hardened steel wire we offer different possibilities to adapt to the needs of each customer, such as the type of palletisation - square or round - and the orientation of the coil axis - horizontal or vertical axis. Along with these packaging and supply options, at VINCO we have different protection elements to preserve all the properties of our wires during the shipping process: cover, VCI damp-proof paper, VCI damp-proof plastic, phytosanitary packaging, maritime packaging and damp-proof sacks.
In order to determine the finish of the oil-hardened steel wire, a number of properties to be defined at the time of ordering must be taken into account:
On the other hand, in the tolerances section of the technical data sheet we have detailed, according to the wire diameter, the nominal value in millimetres and the admissible deviations registered in the EN 10270-2 Standard. The ovality is another aspect to be taken into account, which must not exceed 50% of the total admissible deviation. Finally, the standard length tolerances are also specified in the same section. Consult our complete technical data sheet and get all the information you need.
