The filter screen is primarily made of stainless steel wire mesh.
Stainless Steel Wire Mesh (Stainless Steel Mesh)
Material: SUS201, 202, 302, 304, 316, 304L, 316L, 321 stainless steel wire
Weaving: Plain weave, twill weave, close weave
Stainless steel wire mesh specifications: 1 mesh - 635 mesh. Closed weave twill weave can reach up to 2800 mesh.
304 stainless steel mesh generally refers to "18-8" (18% chromium, 8% nickel). It is mostly a basic stainless steel alloy, ideal for mesh fabric. It can be exposed outdoors and will not rust or oxidize even when the outside temperature rises to 1400 degrees Fahrenheit.
304L stainless steel mesh is very similar to T-304, the difference being a reduced carbon content, making it easier to weave and re-weld.
316 stainless steel mesh can be stabilized by adding 2% molybdenum. T-316 is an "18-8" alloy. It is less susceptible to corrosion than other chromium-nickel stainless steels in brine, sulfurous water, or halides. Chlorides are a prime example. The most valuable characteristic of T-316 is its superior creep resistance at elevated temperatures. Other mechanical properties and structural features are the same as T-304.
316L stainless steel mesh is very similar to T-316, the difference being a reduced carbon content, which facilitates weaving and re-welding.
Applications: Due to its acid and alkali resistance, wear resistance, and temperature resistance, stainless steel is commonly used for screening (screens) and filtration (filters) in acidic and alkaline environments. It is also used as mud screens in the petroleum industry, as filter screens in the chemical and fiber industries, and as pickling screens in the electroplating industry.
