Material page for plain weave wire mesh in Monel 400. The marine and chemical-processing specialist alloy. Covers the grade designation (UNS N04400 (2.4360)), corrosion and magnetic behavior, cleaning and compatibility notes, and the specifications available.
Why Choose Monel 400 for Plain Weave Wire Mesh
The marine and chemical-processing specialist alloy. For plain weave wire 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 plain weave wire 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.
