304Cu Skinpass / Soap-coated Fastener Nail Wire Stainless Steel Wire For Screw And Bolt(0.1-12mm Range Available)

Our Topone 304Cu Stainless Steel Wire is produced from high-quality billets (Qingshan/Yongxing) for reliable and consistent performance in cold heading and screw machining applications. We supply this grade in a full size spectrum from 0.1mm to 12mm.

This wire features excellent formability, high ductility, and is bright annealed for a clean, ready-to-use surface. It is specifically formulated for work-hardening to ensure strong and durable finished parts.
The high copper content in 304Cu enhances its corrosion resistance and mechanical properties, resulting in superior quality and performance. Additionally, an exclusive Skinpass surface option is available for improved smoothness and 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.
