Material page for sintered metal powder filters 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 Sintered Metal Powder Filters
The marine and chemical-processing specialist alloy. For sintered metal powder filters, 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 sintered metal powder filters 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.

Ordering Sintered Metal Powder Filters in Monel 400
- Powder & alloy: SS316L for corrosion; bronze for low-cost pneumatics; nickel alloys for aggressive media.
- Pore size: 0.5–100 µm; specify liquid or gas rating.
- Shape: Tubes, cups, discs or plates with welded or threaded fittings.
Mistakes to Avoid with Sintered Metal Powder Filters
- Choosing too fine a grade for the allowable pressure drop.
- Threading porous parts directly, which cracks them.
