Quotation Information for Sintered Stainless Steel Filter Element
To provide you with an accurate quotation for the stainless steel powder sintered filter element, we kindly request the following key parameters. For more precise customization, attaching drawings or samples is highly recommended:
Filter Diameter: The outer and inner diameter of the filter element, which determines its installation compatibility.
Filtration Precision: Required pore size (ranging from 0.5μm to 100μm) based on your filtration targets.
Material Grade: Preferred stainless steel type, such as 304, 316, or 316L austenitic stainless steel.
Filter Length: Custom length to fit your filtration equipment and system space.
2. Core Advantages of Sintered Filter Element
What makes the stainless steel powder sintered filter element a top choice for industrial filtration? Its core advantages address the most critical needs of various industries:
Superior Mechanical Strength: It boasts extremely high compressive and impact resistance, ensuring stable performance even in high-pressure working environments.
Heat-Resistant & Sterilizable: It can withstand high-temperature processing and repeated sterilization. For example, 316L models tolerate 121°C steam sterilization (SIP), making them ideal for sterile industries.
Precise Pore Size Control: Filtration precision can be controlled as low as 0.5μm, effectively intercepting tiny particles while maintaining uniform flow rates.
Easy to Clean & Reusable: The durable structure supports cleaning methods like backwashing, steam sterilization, and chemical cleaning, extending service life and reducing replacement costs.

In sterile pharmaceutical processes, the stainless steel powder sintered filter element is essential for sterile process gas filtration, such as filtering the intake air of fermentation tanks. Key specifications:
Material: 316L stainless steel with electrolytic polishing (surface roughness Ra ≤ 0.5μm) to avoid bacterial adhesion.
Compliance: Meets FDA 21 CFR Part 211 standards, ensuring pharmaceutical safety.
Sterilization: Withstands 121°C steam-in-place (SIP) sterilization, suitable for strict sterile production environments.
3.2 Aerospace Industry
It serves as a protection filter for aircraft hydraulic oil particle counters, a critical component for flight safety. Key features:
Structure: Sintered titanium alloy reinforced stainless steel, enhancing overall durability.
Performance: Resists pressure up to 50MPa+, tolerates fatigue vibration, and uses 3μm precision to intercept metal wear particles in hydraulic oil.
3.3 Chemical Fiber Industry
As a pre-filter for chemical fiber spinning components (e.g., in PA66 production), it effectively improves spinning quality. Key advantages:
Structure: Multi-layer gradient sintered design (20μm → 5μm) for progressive filtration, ensuring thorough impurity removal.
Resistance: Withstands temperatures above 300°C and resists ester solvents, significantly extending the lifespan of spinnerets.
3.4 Nuclear Industry
The 304L stainless steel filter cartridge (with ultra-low cobalt content) is used for filtering suspended boric acid, preventing contamination by neutron activation products and ensuring safe nuclear facility operation.
