Explore AISI 304 stainless steel wire with excellent corrosion resistance, strength, and formability. Ideal for mesh, fasteners, springs, and welding. Supplied by SUNNING STEEL in custom sizes and finishes.
Among stainless steel wire grades, AISI 304 stands out as the most popular choice due to its superior corrosion resistance, workability, long lifespan, and cost-effectiveness. As an austenitic stainless steel, 304 wire contains a high percentage of chromium and nickel, making it suitable for a wide range of applications in both industrial and domestic settings.
At SUNNING STEEL, we supply AISI 304 stainless steel wire in various diameters, finishes, and forms, including soft annealed and hard drawn, tailored to meet specific performance requirements for welding, mesh production, springs, fasteners, and more.

In its annealed state, 304 stainless steel is non-magnetic, but it may develop slight magnetism after cold working.
Mechanical Properties
(Annealed condition, typical values)
While no metal is completely "rust-proof," 304 stainless steel offers excellent resistance to most forms of corrosion, especially in normal atmospheric and mild chemical environments.
Bright finish is ideal for aesthetic or visible parts, while pickled finish is suited for industrial use. SUNNING STEEL can recommend finishes based on your specific application.
Yes, SUNNING STEEL offers flexible packaging solutions including spools, coils, or custom-cut straight lengths with personalized labels and export-standard packaging.
