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
✔ 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
