2507 Super Duplex Stainless Steel Wire Mesh combines strength and corrosion resistance through its dual-phase structure of austenitic and ferritic stainless steels. Its high chromium, molybdenum, and nitrogen content ensure resistance to pitting, crevice corrosion, and stress corrosion cracking, ideal for marine, chemical processing, and oil & gas industries. This mesh excels in filtration, separation, and reinforcement tasks, making it versatile for harsh environments. Its exceptional durability and performance make it a preferred choice for demanding applications.

Notes

• Versatility: Adapts mesh to specific applications, from fine particle filtration to heavy-duty reinforcement.
• Efficiency: Optimizes filtration performance and material usage by matching mesh specifications to exact requirements.
• Reduced Waste: Minimizes leftover mesh by obtaining custom lengths that precisely fit the project.
• Pricing typically increases with lower mesh counts (coarser), smaller wire diameters (thinner), and larger roll widths or custom lengths due to additional production setup costs.
