Properties of stainless steel sintered porous materials:
- High-temperature resistance, in normal use under 500 ℃.
- High mechanical strength, good plasticity, can be machined.
- Corrosion resistance, oxidation resistance, can be used in nitric
acid, sulfuric acid, dilute hydrochloric acid (5%), acetic acid,
liquid hydrogen, liquid nitrogen environment.
- Good molding process, according to customer drawings for processing
a molding.
- High filtration precision and good purification effect.
- The pores are uniform, the internal structure is stable, and no
particles fall off.
- Good air permeability, easy to back blow cleaning, can be used
repeatedly online regeneration.

Application of stainless steel sintered porous materials
According to its physical and structural characteristics,
stainless steel sintered porous materials are mostly used in the
fields of noise elimination, filtration and separation, fluid
distribution, flow-limiting, capillary core and so on.
- The chemical raw material production process in addition to
impurity filtration, material decarburization filtration, and fine
filtration.
- Ultrafiltration, RO, EDI system security filtration in water
treatment.
- The food and beverage industry finished product clarification
filtration.
- Filtration and recovery of the precious metal catalyst in the
petrochemical industry.
- Precision filtration of liquid raw materials, products and
pharmaceutical intermediates in the chemical industry.
- Reverse osmosis security filtration in the field of water injection
filtration.
- Gas purification of steam, compressed air deoiling purification.
- Medium purification and flow limitation for pneumatic components,
lubricants, fuels, and hydraulic pressure systems.
- Chemical dye industry of high - temperature decarburization.
Precautions for the use of stainless steel sintered porous
materials
- During installation, disassembly and clean avoid scratches,
collisions and falls on hard objects.
- When using, the filtrate is filtered from the outside in to avoid
the reverse direction.
- Avoid instant pressurization when the filter element works.
- When the filtration efficiency is less than 50%, the filter element
should be cleaned in time.
- When cleaning the filter element, the first backflow with pure gas,
back blow pressure is 1.5 times the working pressure, each time for
3-5 seconds, and 4-6 times, then backwash with clean liquid for 3-5
minutes, repeat 2-3 times.
- If the filter element is not good after online back blowing and
backwashing, it should be removed and cleaned in time.
