China 325 Mesh SS304 Filter Mesh Sieve Manufacturer and Supplier

325 Mesh SS304 Filter Mesh Sieve

Mesh: 200/280/300/325/400

Material: 304/316/304L/316L

Diameter/Width: 1.2 m/1 m

Our precision filter mesh is crafted from premium 304 and 316L stainless steel, engineered for durability in harsh environments.

304 stainless steel (18% Cr, 8% Ni) offers excellent corrosion resistance in nitric acid (≤65% concentration) and alkali solutions, making it ideal for general industrial filtration.
316L stainless steel (16-18% Cr, 10-14% Ni, 2-3% Mo) enhances corrosion resistance by 50% compared to 304, withstanding saltwater, sulfuric acid, and marine/chemical industrial atmospheres.

Both grades meet ASTM B117 5000-hour salt spray test standards, ensuring long-term reliability.

Mesh Count: 280-400 mesh (corresponding pore sizes: 53-33 μm), compliant with ISO 3310-1 for precise particle control.
Weave Type: Twill weave structure, allowing thicker wire diameters (0.02-0.07mm) for higher tensile strength (≥500 MPa) and stable filtration performance.
Dimensions: Standard width 1m/1.2m (customizable up to 2.5m); roll length 30m (custom cuts available).
Temperature Resistance: Continuous use at -20°C to 480°C; instant high-temperature resistance up to 1200°C (aerospace-grade applications).
