Spring wires in grades SM and SH

Spring wires in grades SM and SH produced by SBN RUNOWO offer enhanced mechanical properties and increased corrosion resistance. These products are manufactured using technology that does not use any heavy metals (e.g., zinc or nickel, which are used in traditional technologies), thus avoiding the generation of waste containing these metals and simultaneously ensuring the products themselves are free from them. These properties of spring wires are sought after by customers and align with current market trends. The innovative spring wires offered by SBN RUNOWO are characterized by parameters significantly exceeding those of similar products currently available on both domestic and international markets.

Spring wires produced by SBN RUNOWO, particularly those in the SH grade, are a response to current market needs, consistent with the latest trends, for a technologically advanced product for use in numerous industries, such as high-carbon steel spring wire.

Thanks to the technology developed by SBN RUNOWO, it is now possible to produce spring wires with uniform, improved mechanical and technological properties and reduced residual stresses, which is crucial for this type of product, opening up new application possibilities, for example, in the area of ​​low-coil springs.
