Introduction of Stainless Steel Filter
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. Sintered stainless steel filter which most common materials are highly alloyed INOX/AISI316 types, but there are also nickel-based SS varieties and titanium.
- Stainless steel 316L
- Stainless steel 304
- Nickel-based Stainless Steel
- Titanium
During the production of porous 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.
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 SS parts produced from irregularly shaped SS powder, general AISI316L. They are stronger than bronze filters because of the powder’s irregular shape. They are also suitable for higher temperatures.

Application usages
All of the benefits listed above and several others make sintered porous stainless steel filter as an excellent choice for a wide range of applications, including:
- Oil & Gas: The oil and gas industry can use diffusion bonded wire cloth for efficient sand control over numerous types of formation sands, as well as for multiple gravel-pack applications.
- Fluidization: Use sintered wire cloth for fluidizing bulk powders and solids under the most challenging conditions, such as extreme-temperature and high-corrosion environments.
- Power generation: Diffusion bonded wire cloth can maximize the performance of power generation filtration systems for applications such as reactor water cleanup and fuel pool cleanup. It can also help to lower the operating costs in condensate filter and polishing systems.
- General industry: General industrial applications of sintered wire cloth include catalyst recovery, steam filtration, polymer filtration, demineralizing and many others.
