Monel 400 five-layer sintered mesh combines the construction of five-layer sintered mesh (ISO 4022) with the properties of UNS N04400 (2.4360): excellent resistance to seawater, hydrofluoric acid and alkalis, slightly magnetic, service to approx. +540 °C. This page summarizes the grade data, its behavior in filtration service, comparable alloys, and the specifications supplied.
Why Choose Monel 400 for Five-Layer Sintered Mesh
The marine and chemical-processing specialist alloy. For five-layer sintered 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 five-layer sintered 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.
Comparable Alloys
Between the special alloys, selection is chemistry-led: Monel 400 (HF, seawater), Inconel 600 (heat/oxidation), Hastelloy C-276 (broadest acid resistance), nickel 200 (caustic), titanium (chlorides, weight). 316L remains the cost benchmark — specify a special alloy only when the datasheet chemistry demands it.
