304 / 304L Stainless Steel Wire
Stellanox Steel supplies high-grade 304 / 304L Stainless Steel Wire, known for its exceptional corrosion resistance, excellent formability, and wide range of industrial and commercial applications. As one of the most commonly used stainless steel wire grades, 304 / 304L wire is ideal for weaving, welding, tying, and forming in various industries including food processing, automotive, petrochemical, and construction.
The “L” variant offers enhanced weldability and protection against intergranular corrosion due to its lower carbon content.
What is 304 / 304L Stainless Steel Wire?
304 / 304L Stainless Steel Wire is an austenitic chromium-nickel stainless steel alloy available in soft annealed, spring hard, or cold-drawn conditions. It provides an excellent balance of strength, corrosion resistance, and ease of fabrication. The wire form is manufactured with tight dimensional tolerances and is available in round, flat, square, or custom profiles.
Thanks to its hygienic and non-reactive properties, 304 / 304L wire is a popular choice for mesh, filters, wire ropes, fasteners, and welding rods.

Key Features of 304 / 304L Stainless Steel Wire
- Excellent Corrosion Resistance: Performs well in atmospheric, fresh water, and mild chemical environments.
- Low Carbon (304L): Reduces carbide precipitation, making it safe for welding without post-treatment.
- Superior Formability: Ideal for wire forming, weaving, bending, and coiling.
- Non-Magnetic (Annealed): Generally non-magnetic unless cold worked.
- High Ductility: Suitable for spring applications and dynamic movement.
- FDA-Approved: Safe for use in food and medical applications.
