304HC3 Stainless Steel Screw Machine Wire - 3.5mm (0.1-12mm Range Available)

Topone's 304HC3 Stainless Steel Screw Machine Wire represents the pinnacle of quality for high-speed cold heading and screw manufacturing. Specifically formulated for work-hardening applications, this wire ensures exceptional performance in producing durable, precise, and corrosion-resistant fasteners. Our commitment to quality begins at the source, utilizing premium-grade billets from Qingshan Steel Group and Yongxing Special Materials -- two of China's most reputable stainless steel producers. This batch guarantees a consistent 3.5mm diameter, with our capabilities extending across a comprehensive spectrum from a fine 0.1mm to a heavy-duty 12mm.

Key Advantages

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.

Applications (应用)

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.
