Specifications of Duplex 2205 stainless steel wire mesh
Chemical Composition (Typical)
The alloy primarily consists of chromium (approximately 22–23%), nickel (4.5–6.5%), and molybdenum (3.0–3.5%), with nitrogen addition (0.14–0.20%) to enhance mechanical strength and pitting corrosion resistance.
Wire Diameter
Available wire diameter ranges from 0.025 mm to 2.2 mm, depending on mesh count and application requirements.Custom wire diameters are available upon request.
Mesh Count / Opening
Mesh count options typically range from 1 mesh to 400 mesh, covering coarse screening to fine filtration applications.Aperture size can be customized from micron-level openings to several millimeters based on filtration or separation requirements.
Weave Type
Standard weave patterns include plain weave, twill weave, Dutch weave, and twilled Dutch weave.Special weave structures can be supplied according to specific filtration or mechanical performance needs.Plain weave offers uniform openings and general-purpose use, twill weave supports higher mesh counts, while Dutch and twilled Dutch weaves are ideal for fine and ultra-fine filtration applications.
Mesh Width and Length
Standard roll widths include 1.0 m, 1.2 m, and 1.5 m, with customized widths available up to 2.0 m or more.
Typical roll length is 30 m, while cut-to-size sheets or special lengths are available upon request.
Service Temperature
Recommended for continuous service at moderate temperatures.For long-term applications, operating temperatures are generally advised to remain below approximately 300°C to maintain optimal mechanical properties and corrosion resistance.
Surface Finish
Supplied in standard industrial finish.Optional surface treatments such as pickling, passivation, or polishing are available upon request.
Supply Form
Available in rolls or cut sheets.Further fabrication such as cutting, forming, welding, or conversion into filter elements, cylinders, and screens can be provided.
Key Advantages of Duplex 2205 stainless steel wire mesh

High Mechanical Strength
Its yield strength is approximately twice that of 316 stainless steel, allowing thinner wire diameters while maintaining high load-bearing capacity.
Long Service Life
The material maintains stable performance even in harsh operating conditions, reducing downtime and replacement costs.
Versatile Fabrication Options
Available in various wire diameters, mesh counts, and weave patterns, suitable for filtration, separation, and protection applications.
Applications of Duplex 2205 stainless steel wire mesh
Oil and Gas Industry
Duplex 2205 stainless steel wire mesh is widely used in oil and gas production and processing due to its high strength and excellent resistance to chloride-induced corrosion and stress corrosion cracking. It is commonly applied in filtration systems, sand control screens, and protective mesh components.
Chemical and Petrochemical Industry
In chemical and petrochemical processing, Duplex 2205 wire mesh is used for filtration, separation, and screening in corrosive environments involving acids, alkalis, and chloride-containing solutions. It offers longer service life compared with 316 stainless steel.
Marine and Seawater Applications
Duplex 2205 stainless steel wire mesh is highly suitable for seawater filtration, desalination systems, and offshore structures due to its strong resistance to pitting and crevice corrosion in marine environments.
Industrial Filtration and Separation
Duplex 2205 wire mesh is commonly used in liquid and gas filtration systems where both mechanical strength and corrosion resistance are required. It maintains dimensional stability under high pressure and flow conditions.
Architecture and Structural Applications
With its high strength and good corrosion resistance, Duplex 2205 stainless steel wire mesh is used in architectural facades, safety barriers, railing infill panels, and structural reinforcement where durability and aesthetics are required.
Food and Pharmaceutical Equipment
Duplex 2205 stainless steel wire mesh can be used in food and pharmaceutical processing equipment where higher mechanical strength and corrosion resistance are needed, provided that hygiene and surface finish requirements are met.
