304 Stainless Steel 20 Mesh Wire

Common grades include 304, the most widely used general-purpose grade offering good corrosion resistance and formability, and 316/316L, which contains molybdenum for superior resistance to chlorides and harsh chemical environments. Grade selection depends on application demands such as exposure to acids, saltwater, or high-temperature processing conditions requiring specific corrosion performance.

Stainless steel mesh is available in various forms including fine wire cloth for filtration (down to micron-level openings), medium mesh counts like 10-40 mesh for general screening, and coarser knitted or woven mesh with larger openings for structural or shielding uses. Wire diameter, mesh count, and roll width can be customized to match specific flow, strength, or filtration requirements.

Woven mesh uses interlaced wires in a rigid grid pattern, offering precise, uniform openings ideal for sieving and screening. Knitted mesh interlocks wire loops, producing a flexible, three-dimensional structure with high surface area and stretch capacity up to 300%, making it better suited for filtration, demisting, and shielding applications requiring compressibility and shape adaptability.

Yes, 304 stainless steel offers good resistance to oxidation and corrosion in most atmospheric, food-grade, and mild chemical environments due to its chromium-nickel composition. For applications involving chlorides, saltwater, or aggressive chemicals, 316 or 316L grades provide enhanced resistance and are recommended over standard 304 material.

Minimum order quantities typically start around 100 kg for standard knitted stainless steel mesh products, supplied in roll lengths of approximately 30 meters. Custom widths, wire thicknesses, and mesh openings can be produced to order, with lead times depending on specification complexity and finishing requirements such as crimping or flattening.

Yes, 304 stainless steel mesh maintains structural integrity and corrosion resistance at elevated temperatures, making it suitable for exhaust de-coupling, insulation blanket covers, and catalytic converter applications. Its heat resistance combined with flexibility and malleability allows it to perform reliably in demanding thermal environments without significant degradation.
