Alloy 20 Wire Mesh

Description

1. Product Overview
   Alloy 20 Wire Mesh is a high-performance corrosion-resistant woven metal mesh manufactured from Alloy 20 (UNS N08020), a nickel-iron-chromium austenitic alloy engineered for aggressive chemical environments. It is primarily used in chemical processing, pharmaceutical, food processing, and marine industries where resistance to sulfuric acid, chlorides, and pitting corrosion is critical. The key value proposition lies in its exceptional stability under highly corrosive conditions, significantly extending service life and reducing maintenance downtime. Strategically, it is a preferred material for mission-critical filtration, separation, and protective applications where standard stainless steels fail.
2. Key Specifications & Technical Characteristics

• Material Composition: Nickel (32–38%), Chromium (19–21%), Iron balance, with Molybdenum (2–3%) and Copper (3–4%)
• Grade: Alloy 20 / UNS N08020 / Carpenter 20 equivalent
• Form: Woven wire mesh (plain weave, twill weave available)
• Wire Diameter: 0.02 mm – 5.0 mm (customizable)
• Mesh Count: 2 to 400 mesh (application-specific)
• Surface Finish: Bright annealed / electro-polished / pickled
• Corrosion Resistance: Excellent resistance to sulfuric acid, chloride stress cracking, and pitting
• Temperature Resistance: Up to ~600°C under continuous service conditions
• Packaging: Roll form, sheet cut-to-size, wooden crates, or export-standard pallets
• Shelf Life: Indefinite under dry, corrosion-free storage conditions

3. Core Industrial Applications

• Chemical Processing: Filtration and separation of aggressive acids and chemical intermediates
• Pharmaceutical Industry: High-purity filtration systems requiring contamination resistance
• Food & Beverage Processing: Acidic food handling and sterilization environments
• Marine & Offshore Engineering: Corrosion-resistant screening and protective barriers in saltwater exposure
• Pollution Control Systems: Gas-liquid separation and industrial emission filtration
• Superior Performance: Outperforms standard stainless steel meshes (e.g., 304/316) in highly acidic and chloride-rich environments due to enhanced pitting and crevice corrosion resistance, ensuring longer operational cycles and reduced replacement frequency
