​In fields such as marine engineering, chemical processing, and high-end filtration, mesh materials must be resistant to chloride pitting corrosion while also possessing high strength and wear resistance. Duplex stainless steel wire mesh, with its synergistic advantages of austenitic and ferritic two-phase microstructure, has become an important material for meeting these demanding working conditions.Kewei offers sample testing, custom weaving, and material certification support tailored to customer needs, helping engineering clients achieve longer equipment lifespan and lower operating costs in harsh environments. Inquiries regarding technical selection and pricing services are welcome.

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.
