Stainless Steel SINTERED FILTERS

Stainless Steel sintered filters are made from any metallurgical material that is produced as powder. The filters ultimate properties are influenced by the shape, size and distribution of the powder.

The most common materials are highly alloyed Stainless Steel types, but there are also nickel-based Stainless Steel varieties and titanium.

During the production of Stainless Steel sintered filters, the powder is compressed into a mold to create a solid, brittle component. The pore size can be determined by the power that is chosen and the pressing force that is applied.

During Sintering, the powder particles are fused to one another at temperatures well below the melting point of the material. This process gives the highly porous filter their characteristic shape and properties.

After sintering, the size and position of the pores are mechanically fixed. The powder particles also form a rigid whole. This gives the filters a strength, form and stability equal to those of a metal component.

Stainless steel filter are sintered porous Stainless Steel parts produced from irregularly shaped SS powder, GENERALLY AISI 316L.

They are stronger than bronze filters because of the powder's irregular shape. They are also suitable for higher temperatures.
