Porous Sintered Stainless Steel Filter

Sintered stainless steel filter is a porous material produced by compacting and sintering stainless steel powder or by sintering multiple layers of stainless steel wire mesh. The sintering process involves heating the stainless steel material to a temperature just below its melting point, causing the particles or wires to bond together, creating a solid structure with interconnected pores.

Types of Sintered Stainless Filter

Sintered stainless steel can be found in different forms, including:

Sintered Stainless Steel Powder Filters: These filters are made from compacted and sintered stainless steel powder, designed to allow the passage of liquids or gases while retaining solid particles.
Sintered Stainless Steel Mesh: Multiple layers of stainless steel wire mesh are sintered together to create a strong and porous material suitable for various filtration applications.

Materials Used

Sintered stainless steel can be made from various stainless steel grades, including 304, 316, 316L, 904L, among others. The choice of grade depends on the specific application and the required properties, such as corrosion resistance, strength, and temperature resistance.

Techniques

The manufacturing techniques for sintered stainless steel include:

Powder Metallurgy: Stainless steel powder is mixed with other additives, compacted into the desired shape, and then sintered to form a porous structure.
Layered Mesh Sintering: Multiple layers of stainless steel wire mesh are stacked and then sintered together to create a porous material.
