Porous sintered metal filters are constructed from interconnected networks of uniformly distributed pores, creating intricate pathways that effectively capture solid particles present in gas or liquid flow streams. These filters are renowned for their exceptional mechanical strength and serve as outstanding depth filters. Type 316L stainless steel, known for its robustness, can endure temperatures up to 750°F (399°C) in oxidizing environments and 900°F (482°C) in reducing environments.

The production of sintered metal filters involves employing 316L stainless steel powder. The manufacturing process entails the uniaxial compaction of powder within a rigid tool possessing the inverse shape of the desired part, followed by sintering. By adjusting the compaction pressure and/or particle size of the powder, the pore size of the filter can be precisely controlled.
