Alloy20 Wire Mesh Standard UNS N08020 Resists Sulfuric Phosphoric Nitric And Organic Acids
Alloy20 Wire Mesh Standard UNS N08020 Resists Sulfuric Phosphoric Nitric And Organic Acids
Alloy 20 Wire Mesh Introduction:
Alloy 20 wire mesh is crafted from a nickel-iron-chromium superalloy with molybdenum and copper additions, offering:
Primary Composition:
35% Nickel (corrosion resistance)
20% Chromium (oxidation resistance)
3.5% Molybdenum + 2% Copper (acid resistance)
Stabilized with Niobium (Cb) – Prevents carbide precipitation
Key Standards:
ASTM B473 (Alloy 20 Bar & Wire)
ASME SB473 (Pressure Vessel Applications)
Alloy 20 wire mesh delivers optimum performance-to-cost ratio for:
✔ Sulfuric/phosphoric acid systems (where stainless steels fail)
✔ Moderate chloride environments (less severe than seawater)
✔ Applications requiring both corrosion resistance and fabricability
Features:
✔ Unrivaled Corrosion Resistance
Resists sulfuric, phosphoric, nitric, and organic acids
Excellent in chloride and pitting environments (better than 316L SS)
Immune to stress corrosion cracking (SCC)
✔ Mechanical Performance
Tensile Strength: 90-110 ksi (620-760 MPa)
Operating Temp: -325°F to 1000°F (-198°C to 537°C)
✔ Fabrication Advantages
Easier to weld than Hastelloy (no post-weld heat treatment needed)
Good ductility for forming and weaving
Applications:
Chemical Processing
Sulfuric acid concentrator screens
Phosphoric acid reactor filters
Pickling tank components
Pharmaceutical & Food
Citric acid filtration
Vinegar production screens
Bioreactor mesh
Oil & Gas
Downhole screens in sour wells
Flue gas desulfurization (FGD) systems
Pollution Control
Scrubber system meshes
Wastewater treatment filters
