316L Stainless Steel sintered fiber felt combines the construction of sintered fiber felt (ISO 4022) with the properties of AISI 316L (1.4404): superior resistance, including chlorides, brines, food CIP and mild acids, essentially non-magnetic, service to approx. +550 °C continuous. This page summarizes the grade data, its behavior in filtration service, comparable alloys, and the specifications supplied.
Why Choose 316L Stainless Steel for Sintered Fiber Felt
The default filtration and process-industry grade. For sintered fiber felt, 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 sintered fiber felt 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.
Comparable Alloys
Below 316L sits 304 (general purpose, lower cost). Above it: duplex 2205 (strength + chloride resistance), 904L and Hastelloy C-276 (hot chlorides, sulfuric), Monel 400 (HF, seawater), titanium (chlorides at minimum weight) for sintered fiber felt.
