The material used to produce these filters is AISI 316 or AISI 316L stainless steel. They are made by uniaxial compaction of powder in a rigid tool with the negative shape of the part, and then sintered. The pore size is adjusted by changing the compaction pressure and/or the particle size of the powder. They are commonly used in microfiltration of gases and liquids in a dead-end filtration regime.
