Features
product presentation
As a master craftsman in the field of metal wire, we rely on advanced production processes and stringent quality control systems. Using high-quality carbon steel as the core material, we achieve mirror-like smooth surfaces and superior performance through cold drawing, precision heat treatment, and surface finishing techniques. With a perfect balance of micron-level accuracy, high strength, and excellent ductility, as well as outstanding adaptability for subsequent processing, we provide stable and reliable material solutions for precision instruments, automotive manufacturing, construction engineering, and other fields.
Our uncoated steel wire is meticulously controlled at every stage of production through refined processes. By employing special stress-relief treatment and surface purification techniques, we not only endow the product with an exceptionally long fatigue life but also ensure that there are no residual oxide scales on the surface. This lays a solid foundation for subsequent deep processing steps such as plating, painting, and welding, truly achieving "one-time formation, endless possibilities."
core advantage
Mirror surface quality, define the precision benchmark
uncoated steel wire is produced using multi-stage cold drawing combined with precision polishing techniques, controlling surface roughness to ≤Ra 0.1 μm, achieving mirror-like smoothness. This extreme surface treatment significantly reduces friction coefficients, effectively minimizing operational wear, making it particularly suitable for high-precision transmission systems and sealing components where stringent surface quality requirements are essential. The uncoated bare wire design fundamentally avoids the risk of coating peeling, ensuring stability and reliability over long-term use.
Strong and resilient, carrying multiple demands
Selected from high-carbon steel, medium-carbon steel, and low-alloy steel materials, SWRH72A is processed through scientific composition ratios and heat treatment techniques to achieve a tensile strength range of 800MPa to 2200MPa, accurately matching various load conditions. At the same time, it maintains an elongation rate of ≥6%, ensuring moderate ductility while maintaining rigidity. Combined with special stress-relief treatments, this endows the product with excellent fatigue resistance, significantly extending its service life and providing long-lasting stability for critical components.
Flexible customization service, rapid response and delivery
Providing full-diameter coverage from 0.2mm to 20mm, and supporting custom non-standard sections such as flat wires and hexagonal wires, to meet diverse product design requirements. We can offer differentiated process options like annealing and spheroidizing according to customer needs, enabling flexible adjustments in product performance. Leveraging an efficient production management system and rapid response mechanisms, we guarantee sample delivery within 48 hours, providing efficient solutions for urgent projects and customized demands.
