What is 904l stainless steel wire mesh?
904l stainless steel wire mesh is a woven wire mesh where warp and weft (woof / filling) wires are interlaced at right angles. In other words, each warp wire and each weft wire pass over one, two or other amounts of wires, and then under the next one, two or other amounts of wires.
For example, plain woven wire mesh is the mesh where warp and weft wires pass over one, and then under the next adjacent wire in both sides.
In addition, two distinct sets of wires are straight and at right angles to each other.
Weaving type of 904l stainless steel wire mesh
Plain weave, Twill weave, etc.
Weave types are different because of different interlacing of warp and weft wires and different wire diameter.

Material
904L is a super austenitic stainless steel alloy. It’s also referred to as
Euronorm (EN) number | AISI/SAE steel grades | UNS | JIS |
---|---|---|---|
1.4539 | 904L | N08904 | SUS904L |
904L stainless steel chemical composition by weight (%)
AISI/SAE steel grades | Cr Chromium | Ni Nickel | C Carbon | Mn Manganese | Si Silicon | Mo Molybdenum | Others |
---|---|---|---|---|---|---|---|
904L | 19-23 | 23-28 | <0.02 | <2 | <1 | 4-5 |
Mesh metrics: mesh counts, wire diameter and hole size
Mesh counts: 2-200 mesh
Wire diameter: the thickness of one single wire.
Opening / Aperture / Hole size: the distance between two adjacent parallel wires.
Micron size can also tell us something about the mesh. Because it typically refers to the nominal opening size. For example, 70 micron stainless steel mesh has 0.07 mm hole size. 300 micron stainless steel mesh possess 0.3 mm aperture size. From the mesh screen size chart, we can also figure out that 200 mesh to micron is about 73 mm due to its opening size is 0.0737 mm.
904l stainless steel woven wire mesh is customizable
It can be customized as requirement, and it can also be cut, formed, etc.

Characteristic
- Excellent corrosion and rust resistance
- Acid and Alkali resistance
- Inorganic and organic acids resistance
- Good fatigue strength
Applications of 904l stainless steel wire mesh
904L stainless steel wire cloth is primarily used in petrochemical, food processing, oil industries.
904l stainless steel wire meshscreen is commonly used for filtering liquid, separating particle and treating wastewater in the most environments(especially where chemical environment is a must, like high chloride, sulfuric acid, inorganic/organic acid, etc due to its excellent corrosion resistance)
