#400 Mesh – 0.039mm Aperture – 0.025mm Wire Diameter – SS316 Grade – Woven Wire Mesh

#400 Super Fine Marine Grade Mesh 

Our super fine 316 grade stainless steel mesh is designed for precision applications where extreme filtration accuracy and corrosion resistance are paramount. This mesh is particularly suited for medical, pharmaceutical, and scientific industries, where maintaining purity and controlling contamination are essential.

Featuring an exceptionally small aperture size of 0.039mm, this mesh is capable of filtering very fine particulates, making it ideal for high-tech filtration systems, aerosol applications, and precise liquid separation processes. This aperture size ensures that only the smallest particles are allowed to pass through, providing excellent clarity and purity in the filtrate.

The wire diameter of 0.025mm contributes to the mesh’s high tensile strength and durability while maintaining a fine profile, which is crucial for maintaining the integrity of the mesh under the pressure of filtration operations. This fine diameter also allows for a high degree of precision in the weave, crucial for applications requiring consistent and reliable filtration performance.

An open area of 37% offers a balanced approach to filtration, providing sufficient flow rates while maintaining a high level of particle retention. This openness is particularly beneficial in applications where maintaining operational efficiency without sacrificing filtration quality is important, such as in laboratory settings and high-performance industrial filters.

The #400 mesh number indicates a very fine weave, one of the finest available, which is necessary for applications requiring ultra-precise filtration. This fine weave helps to ensure that the mesh can handle very small particles without clogging, thereby extending the lifecycle of the mesh and reducing maintenance needs.

Made from 316 stainless steel, this mesh not only offers superior mechanical properties but also exceptional resistance to corrosion, especially in environments exposed to chemicals, saltwater, and other corrosive agents. The inclusion of molybdenum in its alloy composition significantly enhances its corrosion resistance, making it an ideal choice for harsh or demanding environments.
