UNS N04400 / WNR 2.4360 — Woven & Welded Wire Mesh for Extreme Corrosion Resistance, Custom-Built to Your Specification

• Mesh Count: 3 to 400 mesh
• Wire Diameter: 0.05 mm – 15 mm
• Construction: Woven & Welded
• Weaves: Plain, Twill, Dutch, Twilled Dutch, Five Heddle, Herringbone
• Standard: ASTM E2016-11 | UNS N04400 | WNR 2.4360

We get asked about Monel 400 wire mesh constantly, usually by someone who’s already had a stainless mesh fail on them in a chloride or acid environment. Monel 400 (UNS N04400, WNR 2.4360) is a nickel-copper alloy that keeps working where standard 300-series stainless can’t — seawater, hydrofluoric acid, alkaline solutions, the works. At Kalpataru Piping, we weave and weld this mesh in-house, in counts from a coarse 3 mesh down to a very fine 400 mesh, with wire diameters between 0.05 mm and 15 mm. You can order it in Plain, Twill, Dutch, Twilled Dutch, Five Heddle, or Herringbone weave, depending on what you’re screening or filtering. Every roll leaves our facility with an EN 10204 3.1/3.2 mill test certificate, and most orders go through flexure, compression, and bubble point testing before they’re packed. And if you’re already sourcing Monel 400 pipes and tubes or fittings from us for the rest of the system, this mesh is built to the same UNS N04400 spec, so it slots in without any grade-mismatch headaches.

What Is Monel 400 Wire Mesh?

Monel is technically a trade name — Special Metals originally registered it — but in practice “Monel 400” and “Alloy 400” get used interchangeably, and that’s the material this mesh is woven or welded from. It’s a solid-solution alloy, meaning the nickel and copper are fully dissolved into one another rather than layered or plated on, which is a big part of why it doesn’t lose its corrosion resistance after cutting, welding, or years of abrasion. Compared with stainless mesh, it simply keeps performing in reducing acids, seawater, and hydrofluoric acid service — the exact conditions that chew through 304 or 316 stainless within months.

If your project also needs the wire itself in bar or filler form, our Monel 400 round bars & wires and Monel 400 filler wire pages cover the same UNS N04400 grade.

Monel 400 Wire Mesh Applications & Industries

Where this mesh actually ends up varies a lot, but a few industries account for most of our orders:

• Chemical & Petrochemical Processing: filtration baskets, reactor internals, and strainers that spend their working life in acids and solvents that would eat through stainless in months. Pair it with our Monel 400 buttweld fittings and Monel compression tube fittings for a fully matched system.
• Marine & Shipbuilding: demisters, seawater strainers, and underwater hardware that sits in salt water permanently — this is the classic Monel 400 use case.
• Oil & Gas / Hydrocarbon Processing: crude distillation and refining towers that see corrosive sour gas and hydrocarbon streams day in, day out.
• Boiler Feedwater & Power Plants: feedwater screens and fuel-tank filtration in hot condensate and steam service. Our Monel instrumentation valves and Monel pipe spools are commonly specified alongside this mesh in boiler rooms.
• Aerospace Engineering: components where thermal stability and corrosion resistance both matter, and there’s no room for a material that only does one of the two.
• Pulp, Paper & Mining: vibrating screens and pulp washers that need to survive constant abrasion on top of chloride exposure.
• Industrial Heat Exchangers: support grids, screens, and internals exposed to hot, corrosive process fluid.

Monel 400 vs Stainless Steel vs Hastelloy Wire Mesh

If you’re trying to decide between Monel 400 and something else, it usually comes down to this: stainless mesh is cheaper and fine for general-purpose work, Monel 400 earns its cost the moment chlorides or acids enter the picture, and Hastelloy takes over once you’re dealing with something even Monel can’t handle. Here’s how they stack up side by side.

For a straight stainless option, see our stainless steel wire mesh range; for extreme chemical service beyond what Monel can handle, our Hastelloy wire mesh page has the full spec.

Manufacturing Process & Quality Control

Nothing about this mesh is generic. We start with certified Monel 400 wire rod from mills in India, Japan, and Europe, then draw it down to the exact diameter your mesh count calls for — there’s no shortcut here, since wire diameter is what actually determines opening size and mesh strength. From there it’s either woven on our looms or welded into panels, depending on the construction you need, and crimped — lock, double, intercrimp, or flat-top — to hold its shape under load.

Before anything gets packed, it goes through flexure, compressive, and bubble point testing, and we issue EN 10204 3.1/3.2 certificates along with NABL test reports and a quality assurance plan for every order. For export, that means wooden box packaging; for domestic delivery, HDPE bags or paper tube. Either way, it’s built to arrive exactly the way it left our facility.
