Product Introduction



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.
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.
Metal Stainless Steel powder is pressed in a die at sufficient pressure that the powder particles adhere at their contact points with adequate strength for the formed part to be handled after ejection from the die. Porous metal parts differ from standard P/M structural parts in that they are pressed at lower pressures and may tight mesh cuts of powder in order to achieve specified porosity requirements.
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.
