Topone 304CU (Min. 3% Cu) S-Coated Skinpass Stainless Steel Nail Wire is manufactured from premium billets sourced from leading suppliers such as Qingshan and Yongxing, ensuring consistent and high performance in cold heading and nail production processes. Available in a comprehensive size range from 0.1mm to 12mm diameters, this wire is specially designed for high-speed nail forming and other industrial fastening applications.

This soap-coated nail wire undergoes bright annealing and an exclusive skinpass process, resulting in an exceptionally clean, smooth, and ready-to-use surface with superior formability and high ductility. The 304CU grade, with a minimum copper content of 3%, is engineered to work-harden effectively, delivering strong and reliable finished nails and fasteners. It offers enhanced corrosion resistance and improved mechanical properties compared to standard stainless steel wires.

• Excellent Cold Headability: High ductility and controlled hardening rate minimize cracking and tool wear during high-speed nail forming, ensuring high production yields and extended tool life.
• Exceptional Consistency: Sourced from top-tier mills (Qingshan/Yongxing), the material chemistry and physical properties are uniform across entire batches, guaranteeing reliable performance nail after nail.
• Optimized Surface Finish: The skinpassed and bright annealed surface is clean, smooth, and scale-free, significantly reducing friction and die abrasion while providing an ideal substrate for further processing or bright finishing.
• Enhanced Corrosion Resistance: As a copper-modified chromium-nickel austenitic stainless steel, it offers good resistance to a wide range of atmospheric environments, making it ideal for nails and fasteners in demanding applications.

• Manufacturing of nails, screws, bolts, and other fasteners.
• Cold forging of rivets, pins, and specialized fastening components.
• High-volume production of construction nails, industrial staples, and welding wires.

All Topone 304CU stainless steel nail wire is manufactured under a strict quality management system. Mill Test Certificates (MTCs) certifying chemical composition and mechanical properties are provided with every shipment to ensure full traceability and compliance with international standards.

• Traceable Quality: Raw materials sourced exclusively from renowned mills.
• Precision Engineering: Tight diameter tolerances and consistent mechanical properties tailored for nail making.
• Technical Support: Expert advice on material selection and application optimization.
• Customizable Solutions: Flexible sizing, packaging, and logistics to meet your production needs.
