Product Overview
Stainless steel powder sintered filter element is a precision porous filter material made of stainless steel powder (such as 304, 316L) through cold isostatic pressing and high-temperature vacuum sintering process, with a three-dimensional connected pore structure, which can achieve high-precision filtration and extreme environmental resistance.
Its core benefits include:
1. Excellent filtration performance
High-precision interception: The filtration accuracy covers 0.1–200 microns, and through the deep filtration mechanism, it effectively intercepts bacteria, microorganisms and particulate impurities, and improves the purity of the medium.
Controllable pore structure: The porosity is adjustable (28%–50%), balancing high throughput with low resistance to ensure fluid passage efficiency.
2. Excellent physical properties
Resistant to extreme environments: withstand temperature range of -200°C to 900°C, compressive strength under high pressure conditions ≥30MPa, no deformation and failure.
Strong corrosion resistance: 316L material resists acid and alkali, seawater and chemical media corrosion, extending the service life to more than 5 years.
High mechanical strength: impact resistance, anti-aging, long-term use performance without attenuation
