Product Details
Super duplex stainless steel wire mesh is a kind of an austenitic-ferritic-ferrochromium-nickel alloy woven wire added with molybdenum. It is commonly classified into UNS32750 and UNS31803 based on its chemical composition. Super Duplex stainless steel wire mesh is a highly durable and corrosion-resistant material designed for demanding applications, particularly in environments that require both high strength and superior resistance to corrosion.
UNS32750 super duplex stainless steel wire mesh boasts exceptional resistance to chloride stress-corrosion and fatigue corrosion, along with good plasticity and welding capabilities. It offers remarkable durability and high strength, making it ideal for filter elements in petrochemical, chemical, and desalination industries. Additionally, it finds applications as radiators in automobiles, high-temperature devices, absorption tower devices, and more.
On the other hand, UNS31803 super duplex stainless steel wire mesh exhibits good corrosion resistance, yield strength, welding performance, and high energy absorption. It is extensively used for filtration purposes in pulp, petrochemical, and desalination industries, as well as in food processing equipment, sewage treatment systems, paper bleaching equipment, and similar applications.

Super Duplex Stainless steel wire mesh Applications
Super duplex stainless steel wire mesh finds extensive applications across various sectors including the oil and gas industry for equipment, offshore platforms, diverse heat exchangers, water treatment facilities, chemical industry apparatus, pulp containers, high-corrosion-resistant parts, power plant equipment, and absorption tower devices.
Advantages Over Other Stainless Steel Materials
Higher Strength: Super Duplex stainless steel wire mesh offers superior mechanical properties compared to standard austenitic grades like 304 and 316, making it suitable for more demanding applications.
Improved Corrosion Resistance: Its excellent resistance to pitting, crevice corrosion, and stress corrosion cracking outperforms many other stainless steel grades, especially in chloride-rich environments.
Cost-Effective: While more expensive than standard stainless steels, the longer service life and reduced maintenance costs of Super Duplex stainless steel can make it more cost-effective in the long run.
