2205 duplex stainless steel wire mesh is a high-performance metal mesh product independently developed and produced by our company, crafted from premium 2205 duplex stainless steel wires through precision weaving technology. As a representative of duplex stainless steels, 2205 combines the advantages of austenitic and ferritic stainless steels, boasting exceptional corrosion resistance, high strength, and excellent mechanical properties. It is specifically designed to meet the demanding requirements of harsh industrial environments, making it a reliable choice for critical applications across various sectors.
Material Characteristics
- Outstanding Corrosion Resistance: 2205 duplex stainless steel contains approximately 22% chromium (Cr), 5% nickel (Ni), and 3% molybdenum (Mo), along with a controlled nitrogen (N) content. This unique chemical composition forms a dense and stable passive film on the surface of the woven mesh, enabling it to resist corrosion from a wide range of aggressive media, including chloride solutions, acids, alkalis, and industrial pollutants. It exhibits superior resistance to pitting, crevice corrosion, and stress corrosion cracking compared to many common stainless steels, making it ideal for use in marine environments, chemical processing plants, and wastewater treatment facilities.
- High Strength and Toughness: With a tensile strength of 620 MPa or higher and a yield strength of 450 MPa or more, 2205 duplex stainless steel wire mesh offers significantly higher strength than austenitic stainless steels like 304 and 316. This high strength allows for thinner wire diameters while maintaining structural integrity, reducing weight without compromising performance. Additionally, it retains good toughness even at low temperatures, ensuring reliable operation in cold environments.
- Excellent Heat Resistance: The material maintains its mechanical properties and corrosion resistance at elevated temperatures, making it suitable for applications involving high-temperature fluids or gases. It can withstand continuous operating temperatures up to 300°C, with short-term exposure to higher temperatures possible under specific conditions.
- Good Weldability and Formability: Despite its high strength, 2205 duplex stainless steel has good weldability when proper welding procedures are followed, allowing for easy fabrication and installation of the woven mesh into complex systems. It also offers reasonable formability, enabling customization into various shapes and sizes to meet specific project requirements.
Structural Characteristics
- Precision Weaving for Uniform Mesh: Our 2205 duplex stainless steel wire mesh is produced using advanced weaving equipment and techniques, ensuring uniform mesh size, consistent opening area, and precise filtration accuracy. The tight and regular interlacing of wires guarantees reliable performance in screening, filtering, and separation applications, with minimal variation in mesh parameters across the entire surface.
- Enhanced Structural Stability: The duplex microstructure of 2205 stainless steel, combined with the tight weaving pattern, gives the mesh exceptional structural stability. It is highly resistant to deformation under mechanical stress, pressure, or temperature fluctuations, maintaining its original shape and functionality even in demanding operating conditions. This stability ensures long-term performance and reduces the need for frequent replacement.
- Smooth Surface and Easy Maintenance: The surface of the 2205 stainless steel wire mesh is smooth and free from burrs, minimizing the adhesion of particles, sediments, and contaminants. This feature simplifies cleaning and maintenance, as the mesh can be easily rinsed with water, cleaned with appropriate detergents, or subjected to ultrasonic cleaning. Its resistance to staining and discoloration ensures a long-lasting, aesthetically pleasing appearance.
- Customizable Specifications: To cater to diverse application needs, we offer extensive customization options for 2205 stainless steel wire mesh. This includes varying mesh counts (from fine meshes for precise filtration to coarse meshes for heavy-duty screening), wire diameters, mesh shapes (square, rectangular, etc.), and sheet dimensions. Our engineering team works closely with customers to develop tailored solutions that meet their exact requirements.

Standards & Compliance
2205 duplex stainless steel wire mesh complies with ASTM A240 and corresponds to UNS S32205 / S31803 (EN 1.4462). Its balanced duplex microstructure — roughly 50% austenite and 50% ferrite — combines high strength with superior resistance to chloride pitting and stress corrosion cracking.
FAQ
What is 2205 duplex stainless steel wire mesh?
2205 duplex stainless steel wire mesh is woven from a duplex stainless steel with a balanced microstructure of roughly 50% austenite and 50% ferrite. This gives it nearly twice the strength of 316 and significantly better resistance to chloride pitting and stress corrosion cracking.
What is the difference between 2205 and 316L wire mesh?
2205 is duplex with higher strength (yield ≈ 450 MPa vs ≈ 170 MPa for 316L) and a much higher pitting resistance (PREN ≈ 35 vs ≈ 24). 2205 resists chloride pitting and stress corrosion cracking better, so it is preferred for seawater and chloride service; 316L is sufficient for less aggressive chloride levels.
Why is 2205 called a duplex stainless steel?
2205 has a two-phase (duplex) microstructure of approximately 50% austenite and 50% ferrite. This combination delivers both the corrosion resistance of austenitic steels and the high strength of ferritic steels in a single alloy.
Is 2205 wire mesh resistant to seawater and chlorides?
Yes. With a pitting resistance equivalent number (PREN) of about 35, 2205 resists chloride pitting, crevice corrosion and stress corrosion cracking far better than 304/316. It is widely used in seawater filtration, desalination, offshore and marine applications.
What is 2205 wire mesh used for?
2205 wire mesh is used in offshore and marine filtration, downhole sand control screens, FGD (flue gas desulfurization) scrubbers, chemical processing, seawater desalination and pulp & paper bleach plants — wherever high strength and chloride resistance are required.
What temperature can 2205 wire mesh withstand?
2205 duplex stainless steel wire mesh is generally rated for continuous service up to about 300°C. For higher temperatures, a super duplex grade such as 2507 is recommended.
