904L Stainless Steel Material
904L steel is commonly used in the high-tech, aerospace and chemical industries. Its outstanding corrosion resistance is comparable to that of precious metals. 904L and 316L have the samilar main components are nickel, chromium, molybdenum, but the ratio is different. The biggest difference between 904L and 316L is the content of chrome metal in the material. 904L steel contains more chromium. Chromium can help the surface of metal materials to form anti-corrosion protective film, so the corrosion resistance is stronger than 316L.
AISI304:
Type 304 often refers to as "18-8" (18% chromium, 8% nickel ). T-304 is the basic stainless alloy mostly commonly utilized for wire cloth weaving. It withstands outdoor exposure without rusting and resists oxidation at an elevated temperature up to 1400 Degrees Fahrenheit. Type 304 L is very similar to T-304, the difference being the reduced carbon content for better weaving and secondary welding characteristics.
AISI316:
Type 316: Stabilized by the addition of 2% molybdenum, T-316 is an "18-8" alloy. Type 316 has better resistance to pitting corrosion than the other chromium-nickel stainless steels where brines, sulfur-bearing water or halogen salts, such as chlorides are present. Type 316 L: Type 316 L is very similar to T-316, the difference being the reduced carbon content for better wire cloth weaving and secondary welding characteristics. 316L steel is mainly used in food processing and medical instrument.
AISI 316 L:
Very similar to AISI316, yet with the reduced carbon content for better wire cloth weaving. Woven wire of 316L offers excellent resistance against acid, alkali, heat and corrosion, extensively used in processing of oil, chemical, food, making wire mesh filter, also sorting and screening of solid, liquid and gas in mine, metallurgy, airspace and machine making.
Monel Steel:
The monel steel is also known as Nickel-copper alloy material as its main chemical components are nickel and copper. Monel series material series include Monel400,Monel401, Monel404, MonelR405 and Monel K-500. The most popular monel mesh is made of Monel 400 or Monel K-500.
Monel wire mesh has 60% up of nickel content which offers intense resistance to the variety of corrosion conditions such as resistance to brackish water, steam, salt and caustic solutions. Also, the melting point of Monel material is 1300 to 1350 and this enables Monel wire mesh products suitable for high temperature working conditions. Monel steel mesh is often used in research and development of petroleum and ocean exploring activities.
Weaving: Plain, Twill, Dutch Weave, Five Heddle Weave
Plain Weave Wire Mesh
Among all woven wire products, Plain woven stainless steel wire mesh has the maximum opening and the minimum thickness of the fabric.
Features: Square aperture, high flow through, relative high open area as result of less pressure dro during filtration.
Uses: Plain woven wire cloth is suitable for all kinds of filtration up to 63 µm.
Twill Weave Wire Mesh
Twill weave is applied for weaving of heavy meshes and thicker wire fabric with square opening compared with Plain Weave. Each weft wire passes over two and under two warp wires, and each warp wire passes over and under two weft wires. The wire diameter for both (warp and weft) is mostly the same. Twill Weave allows a thicker wire and is suitable for heavy meshes. The wire position of Twill weave wire mesh is less stable compared with plain weave.
Features: Twill woven wire mesh has square aperture, it is less rigid than plain weave, easy deforming. It is a strong wire cloth due to ratio of wire diameter and aperture.
Uses: Twill woven wire mesh is mostly used for filtration between 25 to 130 μm, processed into discs, packs, filter baskets or various filter elements.
Dutch ( Plain) Weave Wire Mesh
Dutch plain woven wire mesh has straight warp wires and close weft wires. The weft wires lie as close as possible against each other in a linen weave forming a dense strong material with small, irregular and twisting passageways that appear triangular when diagonally viewing the weave .
Compared with normal Plain Weave, the warp wires of the Dutch Plain are larger in diameter than the weft wires. This allows a greater mesh count in the weft direction for the Dutch Plain Woven wire products. Plain Dutch Weave is similar to plain weave, while the warp wires are thicker and lie closer to each other.
Features: Dutch plain woven wire is more solid than square or rectangular mesh, offering relatively high open area, suitable for all kinds of pressure filtration.
Uses:
1, Industrial filter cloth and apparatus of separation;
2, Gas and liquid filtration and other medium separation;
3, Precision pressure filters, the fuel filter, vacuum filter, as filter materials, aerospace, oil refining, pharmaceutical, sugaring, oil, chemical, chemical fiber, rubber, tire manufacturing, metallurgy, food, health research,etc.
Dutch (Twill) Weave Wire Mesh
Dutch Twill also known as Crossed twilled wire mesh. This type of woven wire mesh is a kind of twilled woven wire product combined with the Hollander Weave or Dutch weave. This pattern enables a strong wire cloth with super fine filtration. Compared with common Twill Weave, the Dutch twill allows a thick structure and a fine filter material.
Features: Dutch twill woven ss mesh is rigid, stable and robust.
Uses: For the production of filter disk screen and filter cartridges, used in chemical industry, medicine, petroleum, telecom-communication, scientific research units and so on.
Dutch Weave (Reverse Dutch Weave) Wire Mesh
Reverse Dutch weave is applied for optimizing filtering media manufacture thanks to a high percentage crossing/opening surface. By varying the combination of weft and warp wires, filtering ratings from 14 to 100 microns can be obtained, with an available crossing or opening surface of 30-40%, the maximum yield in similar conditions.
Compared with Plain and Twill weave wire mesh, Dutch Reverse Wire Mesh (actually all the Dutch woven wire mesh) has an improved mesh thickness, filteration precision and service life. The warp wire, weft wire and density have great contrast which enables an excellent filteration under strains and pressure.
Features:
Acid proof, alkali proof, high temperature resistance, high resistance to wear, fine iltering performance, high precision,etc.
Uses: Reverse Dutch Woven Wire Mesh is applicable in a variety of extruders such as PP, HDPE, LDPE, PS as filter screen
Five-Heddle Woven Wire Mesh
Multi-heddle weaving pattern, features a smooth top surface and an open lower surface of the woven wire mesh. This type of woven filter mesh is ideal to conduct accurate filteration under high mechanical strength. Popular meshes are 108x59mesh, 11060mesh and 38x38mesh.
Uses: Mostly as filter belts / ribbons / cut strips for industries include aviation, aerospace, printing, dyeing, electronics, mining, pharmaceutical, food, processing and chemical industry.
