Typical Applications of 316 Twill Dutch Weave Mesh
Twill Dutch weave combines 2/2 twill interlacing with coarse warp wires and tightly packed fine shute wires, forming wedge-shaped pores that hold particles at the surface of the cloth. The 2-3% molybdenum in 316 resists chloride pitting at the same time. Buyers specify this family for high-pressure filtration, catalyst recovery and polymer melt filtration where micron-level retention and corrosion resistance are required together.
- High-pressure filtration
- catalyst recovery
- polymer melt filtration
Metallurgical Composition & Alloy Ratio Analysis
316 Twill Dutch Weave Wire Purity & Heat Traceability
The warp and shute wires for this twill Dutch weave family are cold-drawn from spectrometer-tested 316 rod with the Cr 16-18% / Ni 10-14% / Mo 2-3% balance shown below. Cold drawing raises the wire's yield strength so the tightly packed shute wires stay locked under differential pressure, and each shipment includes an EN 10204 3.1 mill certificate tied to the wire heat number.
All batches are tested via handheld PM-I spectrometer before Tianjin Port export, guaranteeing material compliance.
316 Twill Dutch Weave Physical & Service Limits
- Pitting Resistance (PREN)：Molybdenum 2-3% raises the pitting resistance equivalent number to ~24-26, making this twill Dutch weave mesh the standard choice for chloride-containing polymer melts, brines and process streams where 304 Dutch weave would pit.
- Max Oxidation Temperature：The 316 wire resists scaling in continuous air service up to 870°C and in intermittent service up to 925°C, and molybdenum improves creep strength at elevated temperatures — relevant for hot polymer melt filtration duties.
- Yield Strength After Cold Drawing：The annealed minimum is 205 MPa, rising to about 310 MPa after the cold drawing used for weaving wire, which keeps the tightly packed shute wires and their wedge-shaped pores stable under differential pressure.
- Pressure Service：The dense shute packing gives twill Dutch weave higher strength and aperture stability than plain weave of comparable fineness, which is why it is used in pressure-rated filter elements. Confirm your maximum differential pressure and fluid temperature in the RFQ so we can match wire diameters.
ASTM E2016-22 Reference Tolerances for 316 Twill Dutch Weave
Dutch weave cloth is specified by warp and shute wire diameters as well as mesh count, so confirm which tolerance band in ASTM E2016-22 applies to your specification before ordering. This family's 20-325 mesh range spans the intermediate and fine bands; request actual measured values in the pre-shipment report.
| Nominal Mesh Range | Max Wire Dia. Tolerance | Max Aperture Size Tolerance | Warp Tilt Deviation |
|---|---|---|---|
| 1 to 50 Mesh | ± 0.013 mm (0.0005 inch) | ± 3% of nominal aperture | Tilt deviation ≤ 2° |
| 51 to 200 Mesh | ± 0.008 mm (0.0003 inch) | ± 5% of nominal aperture | Tilt deviation ≤ 1.5° |
| 201 to 400 Mesh | ± 0.004 mm (0.00015 inch) | ± 8% of nominal aperture | Tilt deviation ≤ 1° |
Where Do These Specifications Come From?
- “This specification covers industrial woven wire fabric, referred to as wire cloth, for general use including the separation of particles.”ASTM E2016-22, Scope 1.1ASTM International - mesh count, wire diameter and aperture tolerance basis for this product family
- “This International Standard defines terms regarding industrial woven wire cloth for screening purposes and specifies maximum permissible error, requirements, and test methods.”ISO 9044:2016, ScopeInternational Organization for Standardization - terminology, permissible deviation and test basis for woven wire cloth
- “Twill Dutch - This filter cloth includes a combination of twill and Dutch weave. This uses a technique in which the warp wires that are larger in diameter pass over and under the smaller shute wires. This caused the shute to be closer and results in a filter cloth that is tightly woven and with wedge-shaped or tapered openings.”Newark Wire Cloth, Guide to Different Types of Wire Mesh WeavesNewark Wire - structural definition of twill Dutch weave interlacing used in this page's weave comparison
