AISI 316L or AISI 316 stainless steel filters made by uniaxial compaction
The material used to produce these filters is AISI 316L or AISI 316 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.
