  3. Can Bekaert spring wires be heat-treated?

    down arrow

    Yes, all our wires can be heat-treated in the spring manufacturing process to achieve the high fatigue performance to guarantee the correct dosing during multiple use and the preservation of the spring strength during the device and drugs lifetime. Additionally, our Bezinal coated wires have improved thermal resistance and can be processed at temperatures of up to 300°C (572°F) without impairing product characteristics.

  4. Can pre-coated Bezinal springs be used in devices in direct contact with the drugs or liquids?

    down arrow

    No, Bezinal coated spring wires should be used where contact with drugs or liquids is not possible.

  5. Can steel fibers be added to the readymix plant?

    down arrow

    Yes. Introduce steel fibers after all other ingredients are already in the truck. Set the truck mixer on charging speed and add the fibers slowly into the mixer. Mix for about 5 minutes at charging speed.
    The steel fibers can also be added to the aggregate batch belt, if there is safe access.

  7. How easily can the Bezinal coated springs be cleaned?

    down arrow

    Our spring wires for medical application are manufactured in a strictly controlled environment. On request, specific process conditions can be used that enable easy cleaning of contaminants/residues after spring production. During the spring manufacturing process, specific cleaning agents can be used to get to the required cleanliness for medical application.

  8. How much mixing time is required when adding steel fibers to a ready mix truck?

    down arrow

    Bekaert recommends continuing mixing at the highest drum speed for about 4 to 5 minutes after all steel fibers are added to the truck.

  9. How will steel fibers affect my concrete mix design?

    down arrow

    A properly designed concrete mix is essential for avoiding fiber balling. In order to avoid the potential for fiber balling related to fibers with a high l/d (aspect) ratio (meaning high performing fibers), glued fiber technology has been developed. Glued fiber bundles will spread the glued bundles evenly on “macro level” and during mixing the bundles separate into individual fibers. In essence the glued bundle temporarily lowers the aspect (l/d) ratio of the fibers for easy mixing. That´s how balling can effectively be avoided and a homogenously mix of high performing steel fiber reinforced concrete can be achieved.

  10. Los filtros de fibra metálica Bekipor® son ideales para aplicaciones DPF y GPF. Estas fibras metálicas muy finas y ligeras (diámetro típico entre 17 y 30 µm) permiten altas porosidades (hasta un 88%) y un rendimiento y durabilidad óptimos del filtro.

  12. What is the corrosion resistance of Bezinal coated wires?

    down arrow

    Bekaert has a range of Bezinal coatings that cover a full range of corrosion requirements. We will help you select the optimum coating composition for your specific applications. For some of our Bezinal products, corrosion resistance up to 1000h can be guaranteed, which is in line with the performance requirements of stainless steel. Unlike stainless steels springs, however, there is no risk for crevice corrosion on Bezinal coated wires. The corrosion performance is described in our product leaflets, available via the download section.

  13. What is the elastic modulus of steel spring wires?

    down arrow

    The theoretical e-modulus of all our steel spring wires is 206 MPa. It is considered to be a constant parameter, though it can be optimized depending on our production process. The final e-modulus can deviate slightly from this value. More information can be shared on request.

  14. What is the maximum stress possible in a spring with a steel spring wire?

    down arrow

    There is no straightforward answer to this question, as this depends greatly on the spring design, the post-coiling treatments applied, and the expected fatigue and relaxation performance. The Maximal Allowed Shear Stress (N/mm²) is described in EN 13906-1 (for compression springs), EN 13906-2 (for extension springs), EN 13906-3 (for torsion springs). Detailed calculations and modelling on your specific spring design can be provided by the experts at spring manufacturers.
