Carbon steel wire is a high-strength metal wire made of carbon steel as the base material, formed by rolling, cold drawing or heat treatment process, which is both economical and adaptable in performance. Its carbon content (0.05%~0.8%) can adjust the strength and ductility, and is suitable for multiple scenarios: low-carbon type is flexible and easy to weld, and is used for filter screens and process weaving; high-carbon type has a tensile strength of over 1200MPa, supporting heavy-duty components such as bridge cables, mechanical springs, and automobile clutch plates, and has enhanced corrosion resistance through processes such as galvanizing and plastic coating, becoming the "industrial backbone" in the fields of infrastructure, manufacturing, and people's livelihood.

Low carbon steel wire is made of high-quality low carbon steel with a carbon content of ≤0.25% as the base material, and is refined through cold drawing, annealing and other processes. It has high ductility (elongation 25%-40%) and flexible processing, tensile strength 350-550MPa, hardness HV90-150, welding suitability rate over 90%, and cold bending 180° without cracks. Its cost is 20%-35% lower than that of medium and high carbon steel, and it is widely used in construction binding, agricultural fencing, logistics binding, furniture springs and galvanized filter screens. With its corrosion-resistant coating and forming stability, it has become a cost-effective general metal wire solution.

Medium carbon steel wire uses alloy steel with a carbon content of 0.25%-0.60% as the base material. Through the coupling of hot rolling control, spheroidizing annealing softening and cold drawing deformation strengthening, it achieves a precise match of strength (tensile strength 650-980MPa) and toughness (impact absorption energy ≥25J). The hardness HV180-280 is 1.5 times higher than that of low carbon steel, and the tempering softening temperature is above 350°C. Its core value lies in the balance of strength, ductility and cost, and its adaptation to high fatigue conditions - it can be tempered into high-load elastic components such as automobile suspension springs and agricultural machinery torsion bars, and can also be processed into M12-M30 high-strength bolts, gear transmission shafts and other impact-resistant fasteners after quenching and tempering, combining economy and durability.

The high carbon steel wire contains 0.60%-1.20% carbon.
