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.
