Porous Sintered Components
Sintered stainless steel filters
PORAL designs and manufactures a wide range of stainless steel filters (316L & 304L) with many shapes. Our powder metallurgy and sintering expertise are recognized to meet with the most demanding industrial requirements. Our sintered filters are also alvailable on request with Ni alloys : Inconel 600, Monel 400. Hastelloy X and C276.
Advanced porous filters
Our stainless steel & nickel-based alloys filters
Our range of stainless steel & nickel-based alloys filters is available on many shapes and can work under maximum temperature of 500°C under oxidizing atmosphere and of 600°C under reducing atmosphre. Alloy grades includes SS 316 L and 304 L. Ni alloys are available on request and allow to work under higher temparatures (up to 900°C with Hastelloy).
- Common usage for food application.
- Often used in oxidizing conditions, with nitric or organic acids (except formic and oxalic), with sulphuric, phosphoric or hydrochloric acids.
- Heat resistant.

FAQ about sintered
stainless steel filters.
Are PORAL stainless steel sintered filters food-grade ?
Yes. Stainless steel sintered filters are commonly used in food and beverage applications thanks to their corrosion resistance and ease of cleaning, which supports the hygiene requirements of food-grade processes.
What is the maximum operating temperature for stainless steel vs nickel-alloy filters ?
Stainless steel filters can operate up to 500°C in an oxidizing atmosphere and 600°C in a reducing atmosphere. For higher temperatures, nickel-based alloys such as Hastelloy extend this range up to 900°C.
Can stainless steel sintered filters be used with acidic or corrosive fluids ?
Yes, they perform well in oxidizing conditions with nitric or organic acids (except formic and oxalic acids), as well as with sulphuric, phosphoric, or hydrochloric acids.
Are nickel-based alloy filters (Inconel, Monel, Hastelloy) available in all shapes ?
Yes, all shapes available in the stainless steel range : cartridges, tubes, candles, discs, plates, and cones, can also be manufactured on request in nickel-based alloys such as Inconel, Monel, or Hastelloy.
