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