Product Overview:

Stainless steel sintered discs are integral porous filter components formed by high-temperature sintering of stainless steel powder. With stable pore structure and great mechanical strength, they serve long-term filtration work.


Core Technical Parameters:

Raw Material

AISI 304, AISI 316L low-carbon stainless steel powder (gas atomized grade)

Effective Filtration Pore Rating

0.5μm - 80μm (actual measured pore size, not nominal label)

Bulk Porosity

32% - 45% (higher permeability than laminated sintered mesh)

Max Bearing Pressure

22MPa static pressure, 8MPa alternating dynamic pressure

Continuous Working Temperature

-196℃ ~ 450℃

Surface Treatment

Pickling passivation / electrolytic polishing (Ra≤0.6μm)

Customized Dimensions

Diameter 12mm-350mm, thickness 1.2mm-6mm


Unique Performance Advantages:

1. **Anti-pore displacement stability:** The micropores will not deform or shift under long-term fluid scouring, avoiding a decrease in filtration efficiency. This solves the common problems of mesh loosening and failure in multi-layer sintered filter screens.

2. **Anti-sticky particle clogging:** The tortuous internal pore structure effectively traps fine sticky impurities while maintaining a stable flow rate, making it suitable for filtering high-viscosity fluids.

3. **Multiple regeneration methods:** Supports forward and reverse high-pressure cleaning, heat baking, and ultrasonic deep cleaning, with a regeneration efficiency of over 92% and a service life 3-5 times that of woven filter discs.

4. **Bio-inert:** No metal ion precipitation occurs in neutral and weakly corrosive media; compatible with organic solvents, edible oils, and aqueous solutions.




Target Application Scenarios:

It is widely used in medium-precision solid-liquid and gas-solid separation applications (excluding ultra-sterile pharmaceutical manufacturing). Typical applications include impurity removal from fine chemical raw materials, dewaxing and clarification of edible oils, oil-water separation of compressed air, homogenization of laboratory gases, filtration of electroplating solutions, and purification of impurities in new energy electrolytes. Furthermore, it can also be used as a bottom support filter tray for membrane filter elements.
