304 Stainless Steel Wire Mesh

304 stainless steel is the most versatile and widely used austenitic stainless steel grade. Our 304 wire mesh offers excellent corrosion resistance, superior formability, and outstanding weldability — making it the standard choice for general-purpose wire mesh applications across all industries.

304 stainless steel wire mesh is woven from AISI 304 (UNS S30400) stainless steel wire, containing 18% chromium and 8% nickel. This composition provides excellent corrosion resistance in atmospheric environments, fresh water, and mild chemical exposures.

Our 304 wire mesh is manufactured on precision CNC looms, ensuring consistent mesh count and uniform openings. Every roll undergoes 100% inspection for mesh accuracy, wire diameter, and surface quality before shipping.

Available in three weaving patterns:

Plain Weave — Each warp wire passes alternately over and under each weft wire. Most common and economical pattern.
Twill Weave — Each warp wire passes over two and under two weft wires. Allows heavier wire with finer mesh.
Dutch Weave — Warp wires are heavier, weft wires are finer. Creates very small openings for fine filtration.

Excellent Corrosion Resistance

18% Cr + 8% Ni provides outstanding resistance to atmospheric corrosion, fresh water, and many mild chemicals.

Superior Formability

Austenitic structure allows deep drawing, bending, and stamping without cracking or work hardening issues.

Temperature Resistance

Service temperature range from -196°C to 800°C. Maintains strength and corrosion resistance at elevated temperatures.

Hygienic & Cleanable

Smooth, non-porous surface prevents bacterial adhesion. Ideal for food, pharmaceutical, and sanitary applications.

FAQ

304 SS wire mesh can operate continuously at temperatures up to 870°C (1600°F) in intermittent service and 925°C (1700°F) in continuous service. For cryogenic applications, it remains tough down to -196°C.

304 SS has moderate corrosion resistance in marine environments but is not recommended for continuous saltwater exposure. For marine applications, 316 SS with molybdenum is strongly recommended.

Yes, 304 SS has excellent weldability using all standard welding methods (TIG, MIG, resistance welding). No post-weld annealing is required for most applications, though it may improve corrosion resistance.
