Our Topone 304Cu Stainless Steel Wire is manufactured using premium billets sourced from leading suppliers such as Qingshan and Yongxing, ensuring consistent and high performance in cold heading and screw machining processes. Available in a comprehensive size range from 0.1mm to 12mm diameters, this wire is ideal for a variety of industrial applications.

This soap-coated nail wire undergoes bright annealing, providing a clean, smooth, and ready-to-use surface with exceptional formability and high ductility. The 304Cu grade is specially designed to work-harden effectively, delivering strong and reliable finished components. With a minimum copper content of 3%, it offers enhanced corrosion resistance and improved mechanical properties compared to standard stainless steel wires.

For additional surface refinement, an exclusive Skinpass option is available to achieve superior smoothness and tighter dimensional accuracy.

• Superior Cold Headability: Excellent ductility and controlled hardening rate minimize cracking and tool wear during high-speed forming, ensuring high production yields.
• Exceptional Consistency: Sourced from top-tier mills (Qingshan/Yongxing), the material chemistry and physical properties are uniform across entire batches, guaranteeing reliable performance.
• Optimized Surface Finish: Bright annealed surface is clean, smooth, and scale-free, providing an ideal substrate for plating or leaving as a bright finish. It also reduces friction and die abrasion.
• Enhanced Corrosion Resistance: As a chromium-nickel austenitic stainless steel, it offers good resistance to a wide range of atmospheric and chemical environments.

• Manufacturing of screws, bolts, nuts, and washers.
• Cold forging of rivets, pins, and other custom fasteners.
• Complex cold-headed parts in automotive, aerospace, electronics, and construction industries.

All Topone 304HC3 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.
