Sintered Porous Metal Discs in 316L SS & Titanium
Sintered porous discs in 316L SS or Pure Ti. Inline point-of-use filters, sparger discs, and PEM electrolyzer cell components.
Sintered Porous Metal Discs in 316L SS & Titanium
Diameter range φ5–300 mm (Ti) or φ5–300 mm (SS); thickness 0.5–20 mm (Ti) or 0.5–10 mm (SS). Discs can be pressed to net shape in quantity, or cut from sheet for prototype and small-batch orders.
For PEM electrolyzer use, titanium porous discs in cell-specific diameters serve as porous transport layers — specifying controlled porosity (30–45%) and pore size. For in-line filtration, discs are threaded into pipe unions or pressed into housings for point-of-use particle removal.
Porous metal components for flame-arrestor applications require validation in the complete assembly for the specified gas group, installation, temperature and pressure. Pore size alone does not establish flame-arresting performance. Cleaning and reuse require an agreed procedure and reassessment; no complete-device certification is asserted here.
How to Select a Sintered Porous Metal Disc
Specify whether the disc is used for point-of-use filtration, gas sparging, controlled flow resistance, catalyst support, or a PEM component. Then provide the disc diameter, thickness, required pore range, process medium, temperature, pressure, flow direction, and any sealing or housing details. This establishes whether a net-shape pressed disc or a cut-from-sheet disc is the better manufacturing route.
Choose 316L for standard filtration and pure titanium where corrosion resistance or PEM compatibility is required. For a tubular format with greater filtration area, see sintered porous metal tubes; for larger flat formats, see porous metal plates. For PEM projects, also review FILTURE's hydrogen and PEM application page before submitting a technical RFQ.

Core Advantages of SS/Ti Porous Discs
Wide Diameter Range
φ5 mm instrument-line discs to φ300 mm large-cell electrolyzer components — the same sintering process scales across the full diameter range.
Tight Dimensional Tolerances
±0.1 mm OD and ±0.05 mm thickness as standard. Tighter tolerances for electrolyzer stack components on request.
PEM Stack Components
Ti discs to customer-specified cell geometry, with controlled porosity and pore size, for porous transport layer duty in PEM electrolyzers and fuel cells.
Cleanable and Reusable
Select cleaning chemistry, temperature and reverse-flow pressure for the material and deposited contaminants. Reuse depends on inspection and agreed performance checks after cleaning; unchanged structure or unlimited regeneration is not guaranteed.
Flame-Arrestor Application Review
Porous metal components for flame-arrestor applications require validation in the complete assembly for the specified gas group, installation, temperature and pressure. Pore size alone does not establish flame-arresting performance. Cleaning and reuse require an agreed procedure and reassessment; no complete-device certification is asserted here.
Reinforced-Ring Option
A 1 mm welded outer ring reinforces the disc edge for high-vibration housings and frequent tool changes, without reducing the active filtration area.
Typical Uses for SS/Ti Porous Discs
PEM Electrolyzer PTL Disc
Titanium PTL suitability must be verified for the cell design, electrolyte, electrode potential and temperature. The material name alone does not establish acid resistance or service life.
