Five-Layer Sintered Mesh woven or fabricated in 316L Stainless Steel (AISI 316L (1.4404)) keeps its dimensional specification to ISO 4022; the alloy determines corrosion behavior (superior resistance, including chlorides, brines, food CIP and mild acids) and the service temperature limit (approx. +550 °C continuous). Both are covered below with the full specification table.
Why Choose 316L Stainless Steel for Five-Layer Sintered Mesh
The default filtration and process-industry grade. For five-layer sintered mesh, this matters when superior resistance, including chlorides, brines, food CIP and mild acids is the controlling requirement.
Alloy Properties
| Grade designation | AISI 316L (1.4404) |
|---|---|
| Magnetic response | Essentially non-magnetic |
| Service temperature | approx. +550 °C continuous |
| Corrosion characteristic | Superior resistance, including chlorides, brines, food CIP and mild acids |
Corrosion Behavior in Filtration Service
316/316L adds 2–3% molybdenum to the 304 composition, which sharply improves resistance to chloride pitting and mild acids. For five-layer sintered mesh in marine, brine, food-CIP and chemical-process service, 316L is the default filtration grade; the L (low-carbon) variant also resists sensitization where elements are welded into frames.
Cleaning & Compatibility
Stainless five-layer sintered mesh 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.

Where 316L Stainless Steel Five-Layer Sintered Mesh Is Used
- Fluidized beds & powder handling: air-distribution plates and fluidizing media.
- Chemical & pharmaceutical: Nutsche filter-dryer plates and leaf filters.
- Polymer: melt filter candles and discs.
- Hot gas & steam: high-temperature process filters.
Ordering Five-Layer Sintered Mesh in 316L Stainless Steel
- Micron rating: Absolute ratings of about 1–100 µm set by the filter layer.
- Thickness & strength: Standard laminate is about 1.7 mm and withstands back-wash pressure.
- Form: Sheets, discs, cylinders, cones and welded elements.
Mistakes to Avoid with Five-Layer Sintered Mesh
- Bending the laminate tighter than its minimum radius, which delaminates layers.
- Leaving edge gaps in holders, causing bypass.
