Production process of sintered stainless steel filter
Select high-purity stainless steel powder and make spherical particles by atomization or reduction process.
Fill the mold with powder and form porous blanks by cold isostatic pressing or molding.
Sintering at high temperature (1100-1300°C) in a vacuum or protective atmosphere (e.g. hydrogen) to form a metallurgical bond between particles.
Cutting, welding, and surface polishing of the sintered cartridge.
Ensure the performance is up to standard through bubble point test, permeability tests, compressive strength tests, etc.
Product Advantages
It can work stably under extreme temperature (-200℃ to 500℃) and high pressure (≤20MPa).
Applicable to strong acids, strong alkalis, organic solvents, and other corrosive media (316L material is resistant to chloride corrosion).
Resistance to mechanical shock and alternating pressure, service life up to 5-10 years.
It can be cleaned by ultrasonic cleaning, blowback, or high-temperature calcination to restore the performance and reduce the maintenance cost.
No fiber shedding, in line with FDA, GMP, and other food and pharmaceutical grade health standards.
