Monel 400 hexagonal hole perforated sheet combines the construction of hexagonal hole perforated sheet (DIN 24041 (Hv)) 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 Hexagonal Hole Perforated Sheet
The marine and chemical-processing specialist alloy. For hexagonal hole perforated sheet, 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 |
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.
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.
