Material page for cylindrical filter cartridges in 304 Stainless Steel. The standard general-purpose stainless mesh alloy. Covers the grade designation (AISI 304 (1.4301)), corrosion and magnetic behavior, cleaning and compatibility notes, and the specifications available.
Why Choose 304 Stainless Steel for Cylindrical Filter Cartridges
The standard general-purpose stainless mesh alloy. For cylindrical filter cartridges, this matters when good general corrosion resistance in atmosphere and fresh water is the controlling requirement.
Alloy Properties
| Grade designation | AISI 304 (1.4301) |
|---|---|
| Magnetic response | Essentially non-magnetic (annealed) |
| Service temperature | approx. +450 °C continuous |
| Corrosion characteristic | Good general corrosion resistance in atmosphere and fresh water |
Corrosion Behavior in Filtration Service
304 gives good resistance to atmospheric exposure, fresh water and most neutral media, and is the standard general-purpose grade for cylindrical filter cartridges. In chloride-bearing service (seawater, brines, road-salt spray) step up to 316L; in reducing acids consider a nickel alloy.
Cleaning & Compatibility
Stainless cylindrical filter cartridges can be cleaned by backflush, ultrasonic bath, steam and most CIP chemistry. Two cautions: (1) avoid extended contact with hydrochloric acid or hypochlorite sanitizers, which pit even 316; (2) where the mesh contacts carbon steel during fabrication or service, iron pick-up can rust-stain the surface — specify passivation after fabrication.
