2507 stainless steel wire mesh stands as a premium-grade metal mesh solution, meticulously crafted by our company using top-tier 2507 super duplex stainless steel wires. Renowned as a super duplex stainless steel, 2507 boasts an optimized chemical composition that fuses the best attributes of austenitic and ferritic phases. This unique blend results in exceptional corrosion resistance, extraordinary strength, and remarkable durability, making it the ultimate choice for the most extreme industrial environments where conventional stainless steels fall short.
Material Characteristics
- Exceptional Corrosion Resistance: 2507 stainless steel is formulated with approximately 25% chromium (Cr), 7% nickel (Ni), 4% molybdenum (Mo), and a controlled nitrogen (N) content. This powerful combination creates an extremely robust passive oxide layer on the surface of the woven mesh, enabling it to withstand aggressive media such as high-concentration chloride solutions, sulfuric acid, and seawater with unparalleled efficiency. It exhibits superior resistance to pitting, crevice corrosion, and stress corrosion cracking compared to standard duplex and austenitic stainless steels, making it indispensable in highly corrosive settings.
- Superior Strength and Toughness: With a tensile strength exceeding 800 MPa and a yield strength of over 550 MPa, 2507 stainless steel wire mesh offers significantly higher mechanical strength than 2205 duplex and 316 austenitic stainless steels. This high strength allows for the use of thinner wires without sacrificing structural integrity, reducing weight while maintaining exceptional performance. Additionally, it retains excellent toughness even at low temperatures, ensuring reliable operation in cold climates or cryogenic applications.
- Excellent Heat Resistance: The material maintains its mechanical properties and corrosion resistance at elevated temperatures, withstanding continuous operating temperatures up to 300°C. This makes it suitable for applications involving high-temperature fluids, steam, or industrial processes where heat resistance is a critical requirement.
- Good Wear and Abrasion Resistance: The inherent hardness and strength of 2507 stainless steel 赋予 the woven mesh excellent wear and abrasion resistance. It can withstand the impact of solid particles, turbulent flows, and mechanical friction, ensuring long-term performance in abrasive environments such as mining, mineral processing, and pulp and paper industries.
Structural Characteristics
- Precision Weaving for Consistent Performance: Our 2507 stainless steel wire mesh is manufactured using advanced weaving technology and state-of-the-art equipment, ensuring uniform mesh size, precise opening dimensions, and consistent filtration accuracy. The tight and regular interlacing of wires guarantees reliable performance in screening, filtering, and separation applications, with minimal variation across the entire mesh surface.
- Enhanced Structural Stability: The super duplex microstructure of 2507 stainless steel, combined with the intricate weaving pattern, provides the mesh with exceptional structural stability. It is highly resistant to deformation under mechanical stress, pressure fluctuations, or temperature changes, maintaining its original shape and functionality even in the most demanding operating conditions. This stability ensures long service life and reduces maintenance costs.
- Smooth Surface and Easy Cleaning: The surface of 2507 stainless steel wire mesh is smooth and free from burrs, minimizing the adhesion of contaminants, sediments, and particles. This feature simplifies cleaning and maintenance, as the mesh can be easily rinsed with water, cleaned with appropriate detergents, or subjected to high-pressure cleaning. Its resistance to staining and discoloration ensures a clean and professional appearance over time.
- Customizable Specifications: To meet the diverse needs of various industries, we offer extensive customization options for 2507 stainless steel wire mesh. This includes a wide range of mesh counts (from fine meshes for precise filtration to coarse meshes for heavy-duty applications), wire diameters, mesh shapes (square, rectangular, etc.), and sheet sizes. Our engineering team works closely with customers to develop tailored solutions that perfectly match their specific requirements.

Standards & Compliance
2507 super duplex stainless steel wire mesh complies with ASTM A240 and corresponds to UNS S32750 (EN 1.4410). Its high chromium, molybdenum and nitrogen content give it a pitting resistance equivalent number (PREN) of about 42 — the highest of the standard duplex grades — for the most demanding chloride and seawater environments.
FAQ
What is 2507 super duplex stainless steel wire mesh?
2507 super duplex stainless steel wire mesh is woven from a super duplex alloy (UNS S32750) with high chromium, molybdenum and nitrogen. It has a pitting resistance equivalent number (PREN) of about 42, the highest of the standard duplex grades, for extreme chloride and seawater service.
What is the difference between 2507 and 2205 wire mesh?
2507 is a super duplex grade with a higher PREN (≈ 42 vs ≈ 35 for 2205) and higher strength (yield ≈ 550 MPa vs ≈ 450 MPa). 2507 withstands more aggressive chloride and seawater conditions, while 2205 is a cost-effective choice for less extreme chloride levels.
What is the difference between 2507 and 316L wire mesh?
2507 has a much higher PREN (≈ 42 vs ≈ 24) and roughly three times the yield strength of 316L. It resists chloride pitting, crevice corrosion and stress corrosion cracking far better, so it is chosen for seawater and high-chloride service where 316L would fail.
Is 2507 wire mesh resistant to seawater and high-chloride environments?
Yes. With a PREN of about 42, 2507 is among the most chloride-resistant stainless steels available. It is used in seawater injection, desalination, subsea equipment and acid environments containing chlorides.
What is 2507 wire mesh used for?
2507 wire mesh is used in offshore oil & gas subsea screens, seawater injection systems, desalination, acid regeneration plants, TiO2 chlorination screens, phosphoric acid evaporators and FGD scrubber demisters.
What temperature can 2507 wire mesh withstand?
2507 super duplex stainless steel wire mesh is generally rated for continuous service up to about 300°C, similar to 2205. For higher-temperature chloride service, a nickel alloy such as Hastelloy may be required.
