China [CN] This stainless steel sintered filter disc is manufactured from high-quality 316L stainless steel powder through a high-temperature vacuum sintering process. With a diameter of 19 mm, a thickness of 2 mm, and a filtration accuracy of 5 microns, the product ensures precise control over pore size distribution and porosity. By carefully adjusting the powder ratio and sintering temperature, the porosity is consistently maintained at approximately 35%.
After sintering, the discs are precisely cut using laser technology and undergo edge machining to achieve a smooth, burr-free surface, which facilitates easy installation and enhances sealing performance in practical applications. As a high-performance porous metal component, this filter disc offers exceptional functionality in filtration, aeration, and flame arrestor applications.

Features
High-Precision Filtration
By optimizing the ratio and particle size distribution of 316L stainless steel powder, the filtration accuracy is precisely controlled, achieving a stable 5-micron filtration effect suitable for demanding industrial environments.
Uniform Pore Structure
The sintering process forms a uniform three-dimensional network of pores between powder particles, with porosity consistently controlled at around 35%, ensuring low-pressure loss and high throughput during fluid passage.
Excellent Mechanical Strength: The high-temperature vacuum sintering creates strong metallurgical bonds between powder particles, providing the product with superior compressive and impact resistance, ideal for long-term use under high-pressure differential conditions.
Superior Corrosion Resistance
Made from 316L stainless steel, the filter disc exhibits excellent resistance to acids, alkalis, and chlorides, making it suitable for filtration and treatment of corrosive media in chemical and pharmaceutical industries.
Smooth Edges for Easy Installation
After laser cutting and precision machining, the edges are smooth and burr-free, ensuring easy sealing and installation, thereby improving safety and system stability.
Good Machinability and Customization: The product can be further processed—such as welding or stamping—according to customer requirements, adapting to various equipment interfaces and meeting diverse application needs.
Application Areas
Precision Filtration: Widely used in the petrochemical, pharmaceutical, and water treatment industries for precise filtration of liquids and gases, effectively retaining particles larger than 5 microns to ensure fluid purity.
Aeration Systems: As a core component in aeration systems for wastewater treatment and biological fermentation processes, it releases fine bubbles uniformly, improving oxygen transfer efficiency and promoting biochemical reactions.
Flame Arrestors: Utilizing its microporous structure, it serves as a flame arrestor element to effectively prevent flame propagation, widely applied in flammable and explosive environments such as fuel storage and chemical facilities.
Fluidized Beds and Gas Distribution: In chemical reactors, it functions as a gas distribution plate or fluidized bed component, ensuring uniform gas distribution and enhancing reaction efficiency and system stability.
