For temporary cone & basket strainers in 316L Stainless Steel, the controlling selection factors are the media being filtered, the cleaning regime and the service temperature. The grade data for 316L Stainless Steel is summarized below together with every specification supplied.
Why Choose 316L Stainless Steel for Temporary Cone & Basket Strainers
The default filtration and process-industry grade. For temporary cone & basket strainers, 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 temporary cone & basket strainers 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 temporary cone & basket strainers 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.
