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.

Products 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.
