Material page for y-strainer screens 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 Y-Strainer Screens
The standard general-purpose stainless mesh alloy. For y-strainer screens, 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 y-strainer screens. In chloride-bearing service (seawater, brines, road-salt spray) step up to 316L; in reducing acids consider a nickel alloy.
Comparable Alloys
The direct upgrade from 304 is 316L (chlorides, acids, CIP). Downgrade options for dry, indoor screening are galvanized or plain steel. For heat beyond ~450 °C move to Inconel 600; for seawater immersion consider Monel 400 or duplex 2205 for y-strainer screens.
