Monel mesh for marine and chemical-process designs
Monel woven wire mesh uses a specified nickel-copper alloy in a woven structure for screens, filter supports and technical components. HuiRui offers custom mesh count, wire diameter and finished dimensions to match the design.
Alloy 400 is a common starting point for marine and chemical-processing applications. K-500 adds a different strength and heat-treatment requirement; it should not be selected simply as a more corrosion-resistant version of 400.
- Material requests: Monel 400 and K-500, with grade and condition confirmed for the order.
- Custom geometry: mesh count, wire diameter, opening, width and length.
- Useful service details: fluid chemistry, temperature, flow and any stagnant or fouling conditions.
Monel 400 or K-500?
Use the grade specified by your design. This comparison describes general material behavior, not a guarantee of corrosion performance for the finished mesh.
| Grade | Selection focus | What to confirm |
|---|---|---|
| 400 · UNS N04400 | Nickel-copper alloy widely used in marine and chemical-processing equipment. Strength is influenced by cold work. | Fluid composition, flow, temperature and wire condition. Stagnant seawater can allow localized corrosion. |
| K-500 · UNS N05500 | Nickel-copper alloy with aluminum and titanium additions that allow increased strength and hardness through age hardening. | Required condition, heat treatment and mesh feasibility. In some environments, age-hardened K-500 is more susceptible to stress-corrosion cracking than 400. |
For a K-500 request, include any mechanical-property and heat-treatment requirements. Higher strength does not automatically make it the better corrosion choice.
Custom mesh specification guide
Custom Monel woven-mesh specifications are available. Use the combinations below as starting points for a custom quotation, or send your drawing and application requirements. This is not a stock list.

Select the alloy grade as well as the mesh geometry; each combination is reviewed for the requested grade. Final alloy grade, weave, tolerances and dimensions are confirmed with your quotation.
Calculated nominal opening = 25.4 ÷ mesh count − wire diameter (mm), rounded to 0.0001 mm where needed. These are nominal design calculations, not inspection results, manufacturing tolerances or certified filtration ratings.
This guide uses regular square-opening woven-mesh geometry. Dutch-weave, unequal warp/weft counts and expanded-metal designs require separate specifications.
Choose the weave for your monel mesh
- Plain square weave: an alternating over-and-under pattern with visible openings. Specify mesh count together with wire diameter or target opening.
- Twill square weave: a staggered pattern that produces diagonal lines. It can accommodate different wire-to-opening combinations from plain weave; the final structure is selected with the specification.
- Dutch weave: closely packed wires create a filtration path rather than the visible square openings shown in the guide. Include warp/weft counts, wire sizes or the filtration target for a separate assessment.
Custom weave requests are welcome. Suitability depends on the alloy grade, wire condition and dimensions; not every combination is suitable for every grade.
Specify your custom monel mesh
Start with mesh or opening, finished size and quantity if known. A drawing, reference sample description or short application note is enough to begin.
| Custom requirement | Details to include |
|---|---|
| Alloy grade and condition | Give the exact grade or UNS designation. Include the required wire condition or heat treatment if specified by your design. |
| Mesh, wire and opening | Choose a guide row or request another combination. For square weave, state mesh count and wire diameter, or your target opening. |
| Filtration structure | For Dutch weave, include warp/weft details or your filtration target and process fluid. A calculated square opening is not a filtration rating. |
| Finished dimensions | Width × length, piece or roll format, quantity and any cut-edge or component drawing requirements. |
| Service conditions | Fluid chemistry, concentration, temperature, flow or stagnant conditions, cleaning media and mechanical loading. |
| Inspection and documents | Mention critical tolerances, inspection requirements and material documents needed. The quotation will confirm what can be supplied. |
You do not need every technical detail before contacting us. Final grade, weave, dimensions, tolerances and order requirements are confirmed with your quotation.
Applications and material compatibility
Potential mesh uses include marine strainers, process screens, filter-support layers and laboratory components. Match the material to the complete environment, not only the broad label “seawater” or “chemical service.”
- Marine screening: include water chemistry, flow, fouling and whether the mesh remains wet during shutdown.
- Process filtration: provide the liquid composition, concentration, temperature and cleaning media.
- Filter supports: identify the supported material, required opening and pressure differential.
- Technical development: send a drawing, existing sample description or test conditions for a custom quotation.
Flowing seawater performance should not be used as a promise for stagnant service. Alloy 400 can suffer pitting or crevice attack in stagnant seawater, and K-500 also needs condition-specific corrosion review.

Frequently asked questions
Is Monel mesh suitable for all seawater conditions?
No. Alloy 400 is used in marine service, but stagnant conditions can promote pitting and crevice corrosion. Include flow, temperature, fouling and shutdown conditions when reviewing the material.
Is K-500 always more corrosion-resistant than Monel 400?
No. K-500 is selected for its age-hardening capability and potential strength increase, not a universal corrosion advantage. Age-hardened K-500 can be more prone to stress-corrosion cracking in some environments.
Can mesh count alone define the opening?
No. For square weave, both mesh count and wire diameter determine the nominal opening. Dutch weave uses a different filtration path, so its filtration characteristics must be specified separately.
Can I request a custom size or a different mesh combination?
Yes. Send the grade, opening or mesh count, finished dimensions and quantity if known. A drawing or short application description is also welcome; the final wire and weave combination is confirmed with the quotation.
What should I specify if material records are required?
List the grade identification, material documents and inspection criteria your project needs before ordering. The quotation will confirm the available documentation and the agreed material condition.
