Twill Dutch Weave Mesh woven or fabricated in Monel 400 (UNS N04400 (2.4360)) keeps its dimensional specification to ISO 9044; the alloy determines corrosion behavior (excellent resistance to seawater, hydrofluoric acid and alkalis) and the service temperature limit (approx. +540 °C). Both are covered below with the full specification table.
Why Choose Monel 400 for Twill Dutch Weave Mesh
The marine and chemical-processing specialist alloy. For twill dutch weave mesh, this matters when excellent resistance to seawater, hydrofluoric acid and alkalis is the controlling requirement.
Alloy Properties
| Grade designation | UNS N04400 (2.4360) |
|---|---|
| Magnetic response | Slightly magnetic |
| Service temperature | approx. +540 °C |
| Corrosion characteristic | Excellent resistance to seawater, hydrofluoric acid and alkalis |
Corrosion Behavior in Filtration Service
Nickel-family alloys are specified for twill dutch weave mesh when stainless is not enough: Monel 400 for seawater and hydrofluoric acid, Inconel 600 for oxidation at extreme temperature, Hastelloy C-276 for hot chlorides and mixed acids, titanium for chlorides with weight savings. Match the alloy to the specific chemistry — they are not interchangeable.
Cleaning & Compatibility
Special alloys tolerate aggressive cleaning chemistry, but confirm the specific acid/alkali against the alloy datasheet — e.g. Monel handles HF but not oxidizing nitric; titanium handles nitric but not HF. When welding elements into frames, use matching filler and inert-gas backing to preserve corrosion resistance at the joint.

Where Monel 400 Twill Dutch Weave Mesh Is Used
- Aerospace & hydraulics: servo valve and fuel filters rated 5–40 µm.
- Pharmaceutical & chemical: Nutsche, candle and leaf filters.
- Polymer melt: fine layers in extruder filter packs.
- Gas filtration: instrument and sampling filters.
Ordering Twill Dutch Weave Mesh in Monel 400
- Absolute rating: Specify absolute micron with the test method (e.g. glass-bead or bubble point).
- Count: Counts such as 200 × 1400 or 325 × 2300 define the rating.
- Support: Always pair with a coarser support layer in elements.
Mistakes to Avoid with Twill Dutch Weave Mesh
- Using twill dutch where flow is critical — its open area is low.
- Omitting the support layer, so the cloth deforms under pressure.
