Super Duplex Stainless Steel Wire Mesh Specifications

Wire diameter ranges from 0.01 to 2.03 mm, mesh counts cover 1 to 350 mesh, with twill weave capable of reaching up to 800 mesh. Dutch weave covers 20×250 to 100×800 mesh. Standard widths range from 0.914m to 2m, with support for extra-wide customizations. It can withstand extreme chloride corrosion environments long-term, with strength more than double that of ordinary austenitic stainless steel. 

Classified by weaving process: plain weave Super Duplex Stainless Steel Wire Mesh, twill weave Super Duplex Stainless Steel Wire Mesh, Dutch weave Super Duplex Stainless Steel Wire Mesh; classified by material: S32750 super duplex stainless steel wire mesh, S32760 super duplex stainless steel wire mesh.

Super Duplex Stainless Steel Wire Mesh Core Applications

Widely used in extreme highly corrosive environments such as seawater desalination, oil and gas extraction, chemical POE units, and high-concentration chloride wastewater treatment. It can maintain long-term stable operation under harsh conditions where even regular 2205 duplex steel would fail, making it a core specialized wire mesh component for high-end strong corrosion scenarios.
