Duplex wire mesh

Duplex wire mesh specifications

What is a Duplex wire mesh?

These meshes match applications demanding strength, durability, and corrosion resistance. A duplex wire mesh works in filtering and screening in the chemical, pollution control, and paper production sectors.

Clients can choose a 2205 duplex stainless steel wire mesh with 22% chromium, 5% nickel, and molybdenum. Meshes with more chromium content (i.e., Grade 2507) suit seawater and higher pressures.

How is a duplex wire mesh used in demanding applications such as the oil and gas, chemical, and pulp and paper industries?

Using a duplex steel UNS S31803 wiremesh in trying environments is safe and reliable since it tolerates abrasives and temperatures from -50 to 300°C. A duplex stainless steel wire mesh screen resists chlorides (SCC) and intergranular corrosion.

What are the benefits of using a duplex wire mesh for infrastructure and building projects? How does it compare to other types of mesh?

A duplex 1.4462 wire mesh is a common choice for infrastructure projects due to its lightness and inherent strength (tensile rating of 880 Mpa).

  • Environment-friendly, although aluminium can be lighter and greener
  • Resists crevice corrosion better than standard stainless steel
  • Good weldability, but machining can be challenging
  • Long service life

Which testing methods evaluate the corrosion resistance of a duplex wire mesh? How do these methods inform material selection for different applications?

Corrosion testing for a SAF 2205 duplex stainless steel wiremesh is integral in industrial material selection. We use internationally accepted techniques like IGC and pitting resistance tests. For instance, a S32205 wire mesh has an annual corrosion rate of roughly 0.416 milli-inch.

Clients can request additional electrochemical tests or a third-party inspection

What are the most cost-effective applications for a duplex wire mesh? How do they reduce overall project costs?

The initial costing of a duplex steel woven wiremesh may seem high, but it is cost-effective. It is lighter and stronger than many alternatives, limiting the required project material. A duplex stainless steel spring steel wire mesh is cheaper to transport and dispose, with low total ownership costs.
