What is 904l Stainless Steel Wire Mesh and Why Do We Use Them?

904L Stainless Steel Wire Mesh – Alloy Overview

904L stainless steel wire mesh is a superaustenitic stainless steel alloy originally developed to have excellent corrosion resistance to environments containing dilute sulfuric acid. Today, it is used in a broad range of different process environments, including in both inorganic and organic acid settings. With high chromium (21%), nickel (25.5%), molybdenum (4.5%), and copper (1.5%) content, 904L stainless steel wire mesh possesses great resistance to general corrosion. Its chromium and molybdenum additions further provide 904L with superior resistance to general corrosion, pitting, and chloride stress corrosion cracking as compared to T-316L. In cases where cost is a factor, duplex is often substituted for 904L given its similar corrosion resistance, higher mechanical strength, and lower cost (keep in mind, however, duplex should not be used above 570°F). In cases where both higher corrosion resistance and strength are required, super duplex or ZERON® 100 super duplex are often substituted in place of 904L. Some characteristics of 904L stainless steel wire cloth which dictate its use are:

• Superaustenitic stainless steel.
• Non-magnetic in all conditions.
• Withstands outdoor exposure without rusting.
• Good fatigue strength & excellent corrosion resistance in severe industrial and chemical settings.
• Good resistance to inorganic acids (i.e. hot phosphoric acid) as well as most organic acids.
• Lower resistance to nitric acid vs. T-304L (which is free of molybdenum).
• Best used in temperatures below 750°F (undergoes embrittlement at higher temperatures).
• Easily welded, more difficult to cut and form than T-316L (thus, higher cutting forces are required).

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.

If you are looking for more details, kindly visit 904l Stainless Steel Wire Mesh.

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.

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. mm.
