Knitted Wire Mesh woven or fabricated in 304 Stainless Steel (AISI 304 (1.4301)) keeps its dimensional specification to Industry convention; the alloy determines corrosion behavior (good general corrosion resistance in atmosphere and fresh water) and the service temperature limit (approx. +450 °C continuous). Both are covered below with the full specification table.
Why Choose 304 Stainless Steel for Knitted Wire Mesh
The standard general-purpose stainless mesh alloy. For knitted wire mesh, 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 knitted wire mesh. 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 knitted wire mesh.
