The 316L Stainless Steel Sintered Powder Filter 60×400 is a high-performance porous metal filtration component manufactured from premium 316L stainless steel powder through advanced cold isostatic pressing and high-temperature vacuum sintering technology. This sintered metal filter is engineered for demanding industrial applications requiring exceptional corrosion resistance, thermal stability, and mechanical strength.
The manufacturing process involves pressing precisely graded 316L stainless steel powder into a cylindrical shape, followed by high-temperature vacuum sintering. During sintering, the powder particles fuse at their contact points without completely melting, creating a rigid, three-dimensional matrix with a network of interconnected, tortuous pores. The size of the original powder granules directly dictates the pore size of the final product, allowing for precise engineering of filtration ratings from 0.1 to 50 microns.

This sintered filter is manufactured by Huahang Filter, leveraging expertise in powder sintering technology and metallurgy. We focus on producing reliable, application-specific metal filters. Our controlled sintering process ensures consistent pore structure and performance in every batch. We provide technical support for material selection and can offer custom versions of this platform element with different end fittings, lengths, or surface treatments to meet unique system integration needs.
Controlled Sintering for Consistent Porosity: Our sintering process is finely tuned to create a uniform porous matrix, providing a reliable and predictable absolute filtration rating (e.g., 2, 5, 10, 20, 40 microns) in this small form factor.
Precision Thread Machining: The G¾ threads are machined to exacting standards, ensuring a perfect seal with standard fittings and preventing cross-threading or leakage in critical fluid paths.
High Material Purity & Integrity: We use high-grade 304 or 316L stainless steel powder, resulting in a filter with excellent corrosion resistance and structural integrity suitable for demanding analytical or process applications.
Durability and Cleanability: Despite its small size, the monolithic sintered structure is robust and can be backflushed or ultrasonically cleaned numerous times, offering long-term service life and value.

Q1: What is the porosity of these filters?
A: Standard porosity ranges from 30-50% , providing an excellent balance of strength and flow. High-porosity versions up to 65% are available for applications requiring maximum flow with lower pressure drop .
Q2: Can stainless steel sintered powder filters be cleaned and reused?
A: Yes. One of the primary advantages of sintered powder filters is their reusability. They can be cleaned using:
With proper cleaning, these elements can achieve extended service life and significantly reduce long-term operating costs.
Q3: What end connection types are available for this sintered filter element?
A: We offer multiple connection options to fit most filter housings:
Q4: What is the difference between SS304 and SS316L for this filter element?
A: SS304 offers excellent overall performance at a cost-effective price point, suitable for general industrial applications, water treatment, and less corrosive environments.
SS316L contains molybdenum (2-3%), providing superior resistance to chlorides, saltwater, acids, and aggressive chemicals. The “L” indicates low carbon content, which improves weldability and resistance to intergranular corrosion. Choose SS316L for pharmaceutical, chemical, petrochemical, seawater, and high-corrosion applications.
