Duplex stainless steel mesh combines a ferritic-austenitic microstructure (50% each) to deliver 2X the yield strength of standard 316L stainless wire while maintaining exceptional corrosion resistance. This makes it ideal for:
- Offshore oil & gas equipment
- Chemical processing systems
- Marine and desalination components
- Nuclear power infrastructure
- High-stress aerospace fasteners

Superior Corrosion Resistance
Duplex stainless steel metal wire offers excellent resistance to corrosion, particularly in chloride-rich and marine environments, making it ideal for offshore, chemical, and desalination applications.High Strength-to-Weight Ratio
Duplex grades exhibit nearly twice the tensile strength of standard austenitic stainless steels (e.g., 304, 316), allowing for lighter components without compromising structural integrity.Excellent Stress Corrosion Cracking (SCC) Resistance
The duplex microstructure significantly reduces susceptibility to stress corrosion cracking, especially under high-stress and high-temperature conditions.
Applications Across Industries
- Oil & Gas: Wire for subsea umbilicals, valve springs, safety-critical fasteners.
- Chemical Processing: Catalyst meshes, filtration wire, reactor internals.
- Marine: Anti-fouling nets, cable reinforcement, rigging wire
- Energy: Nuclear fuel assembly wire, heat exchanger springs
- Medical: Surgical tools, orthopedic wire forms
Duplex stainless steel metal mesh combines high strength with excellent corrosion resistance, making it an ideal choice for demanding industrial environments. With a unique dual-phase microstructure of austenite and ferrite, it offers superior mechanical properties compared to standard austenitic stainless steels, including exceptional resistance to stress corrosion cracking, pitting, and crevice corrosion. Its enhanced durability allows for reduced material thickness and weight without compromising performance, offering significant cost savings over the product’s lifecycle.
