High Strength Steel Wire

Extraordinary strength, leading material innovation

Using aerospace-grade materials and carefully adding micro-alloy elements such as vanadium and niobium, a unique process is employed to refine the grain size to the nanometer level (<0.1 μm), achieving an astonishing strength of 4500MPa (data from the 2022 study in *Materials Science & Engineering*). By leveraging tension-controlled drawing technology, internal stress concentration issues are precisely eliminated, while ensuring a stable elongation at break of ≥5%. This results in ultra-high strength with excellent toughness, effectively preventing brittle fracture of the material.

Adapt to extreme conditions and have excellent protective performance

A dual-coating protection system has been constructed, with the inner layer made of zinc-5% aluminum alloy and the outer layer covered with epoxy resin. It has passed a rigorous ASTM B117 standard salt spray test lasting over 3000 hours, capable of withstanding harsh environments such as offshore platforms and chemical plants with high corrosion resistance. The system also performs excellently in low-temperature conditions, passing the Charpy V-notch impact test (ISO 148-1). Even at ultra-low temperatures as low as-60℃, there is no risk of brittleness, ensuring stable performance under various extreme conditions.

Help lighten the load and promote energy optimization

In practical applications, high strength steel wire with a diameter of 5mm can perfectly replace ordinary rebar with a diameter of 12mm. This not only achieves the goal of reducing weight by 70% but also significantly enhances tensile strength by 200% (as shown in the actual case of the XX Cross-Sea Bridge cable project). This lightweight transformation effectively reduces energy consumption during transportation and construction, actively responding to global carbon neutrality goals and contributing to sustainable development.
