The 50μm Stainless Steel Sintered Powder Filter Element 60×52.2 is a high-precision, compact cylindrical filtration component manufactured from 304 or 316L stainless steel metal powder through a specialized high-temperature vacuum sintering process. This sintered powder filter is designed for applications requiring reliable medium-grade filtration in a space-saving package.
The sintering process diffusion-bonds the stainless steel powder particles together, creating a rigid, highly uniform porous structure with interconnected micropores and a filtration accuracy of 50 microns. The 50μm rating makes it ideal for pre-filtration, coarse filtration, and protection of downstream fine filters in hydraulic, pneumatic, and industrial fluid systems.

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 micron ratings are available for stainless steel sintered powder filters?
A: Sintered powder filters are available in a wide range of pore/filtration ratings.
Depending on the manufacturer and production process, commercial products can cover approximately 0.2–100 μm, while some specialized products offer even finer ratings.
Q2: Is 316L better than 304 for sintered powder filters?
A: Not necessarily. The correct choice depends on the application.
304 stainless steel is suitable for many general industrial filtration applications and can offer a lower material cost.
316L stainless steel provides improved corrosion resistance and is often preferred for:
For highly corrosive media, even 316L may not be sufficient, and alloys such as Hastelloy or Inconel may be considered.
Q3: Can stainless steel sintered powder filters withstand high temperatures?
A: Yes. High-temperature resistance is one of the major advantages of sintered metal filters.
Because the filtration medium is made entirely from metal powder, it does not rely on polymeric filter fibers or adhesives that may degrade at elevated temperatures.
However, the actual operating temperature depends on:
For example, current commercial 316L sintered powder cartridges specify operating temperatures around 400°C, while other engineered porous-metal media can operate at substantially higher temperatures depending on alloy and atmosphere.
Q4: Can stainless steel sintered powder filters be used for gas filtration?
A: Yes. They can be used for both gas and liquid filtration.
Gas applications include:
Porous-metal cartridges are also used for high-temperature gases, solvents, chemicals, polymers and pharmaceutical processes.
