Duplex Stainless Steel Mesh

Duplex stainless steel wire mesh is made of duplex stainless steel material, which consists of austenite and ferrite phases.
Super duplex stainless steel wire mesh usually uses a new high-strength duplex stainless steel alloy with higher tensile strength and better corrosion resistance.

Woven type of duplex stainless wire mesh: Plain weave, Twill weave, dutch weave.
Mesh count from 2 mesh – 1400 mesh
Max width of duplex mesh is 4.5m

Our company has stocked Duplex stainless steel wire mesh of 10 mesh, 20 mesh, 30 mesh, 40 mesh, 60 mesh, 80 mesh, 100 mesh, 120 mesh, 150 mesh, and 200 mesh, saving you the high cost and long time of individual customization.

50 micron Dutch weave Duplex stainless steel mesh in stock, the sample can be offered for reference.
Special specifications can be customized according to requirements.

Duplex stainless steel wire cloth material

Duplex Stainless Steel (DSS) refers to stainless steel in which ferrite and austenite each account for about 50%. Generally, the content of the smaller phase needs to be at least 30%. In the case of low C content, the Cr content is 18%~28% and the Ni content is 3%~10%.

This type of steel has the characteristics of both austenitic and ferritic stainless steel. Compared with ferrite, its intergranular corrosion resistance and welding performance are significantly improved. Compared with austenitic stainless steel, it has high strength and significantly improved resistance to intergranular corrosion and chloride stress corrosion.

Duplex stainless steel has excellent pitting corrosion resistance and is also a nickel-saving stainless steel.
2205 duplex stainless steel is an economical corrosion-resistant stainless steel.
2507 super duplex stainless steel has excellent resistance to pitting corrosion, crevice corrosion and uniform corrosion.
