Duplex stainless steel wire meshes, particularly those made from UNS31803 (SAF2205) and UNS32750 (SAF2507), are renowned for their exceptional corrosion resistance and mechanical strength. These properties make them indispensable in various industrial applications where durability and reliability are paramount.
What is UNS31803 and UNS32750 Duplex Stainless Steel?
Duplex stainless steel is a blend of both austenitic and ferritic steels, offering a unique combination of strength, corrosion resistance, and workability. UNS31803 and UNS32750 are two common grades of duplex stainless steel, known for their excellent resistance to pitting, crevice corrosion, and stress corrosion cracking.
UNS31803: Its chemical composition includes Cr(21–23%), Ni(4.5–6.5%), and Mo(2.5–3.5%). These components endow it with excellent resistance to pitting, crevice corrosion, and stress corrosion cracking. The alloy also exhibits high yield strength and superior weldability.
UNS32750: It contains higher levels of Cr(24–26%), Ni(6–8%), and Mo(3–5%), which enhances its resistance to chloride stress corrosion and provides excellent mechanical properties.

Applications of UNS31803 & UNS32750 Duplex Stainless Steel Wire Mesh
•Chemical and Petrochemical Industries: Utilized for filtration and separation processes, ensuring equipment longevity in corrosive environments.
•Desalination Plants: Employed in filtering systems to withstand high salinity and prevent corrosion.
•Food Processing: Applied in equipment requiring stringent hygiene standards and resistance to acidic substances.
•Architecture: Used as decorative facades and security screens, offering both aesthetic appeal and structural integrity.
Conclusion
When choosing wire mesh for applications in harsh environments, UNS31803 and UNS32750 duplex stainless steel wire mesh offer an excellent combination of strength, corrosion resistance, and durability. These materials are ideal for industries ranging from marine to chemical processing, providing long-lasting solutions that stand up to even the toughest conditions.
