Description
Introduction
Description
304 Stainless Steel Filter Bag Cage,A structural support component for dust collector filter bags, crafted from 304 stainless steel (Cr 18-20%, Ni 8-12%) to deliver corrosion resistance, thermal stability (≤400°C), and mechanical durability. Features circumferential/longitudinal ribs for optimized load distribution and airflow uniformity. Compliant with industrial hygiene standards, ideal for applications in chemical, food-grade, and mildly corrosive environments.
Key Features
>Corrosion Resistance
– Contains 18-20% chromium (Cr) and 8-12% nickel (Ni), providing excellent resistance to oxidation, moisture, and weak acids/alkalis common in industrial environments.
>High-Temperature Stability – Thermal Performance: Withstands continuous operating temperatures up to 400°C (752°F) without structural deformation, ensuring reliability in high-heat processes.
>Mechanical Strength – Structural Integrity: Minimum yield strength of 205 MPa and tensile strength of 520 MPa.
>Optimized Rib Design – Reinforced welded ribs ensure uniform airflow distribution, reduce fabric wear, and maintain bag shape during pulse-jet cleaning cycles.
>Surface Finish Options – Electropolishing/Sandblasting: Smooth surface minimizes dust adhesion, enhances corrosion resistance, and extends service life in abrasive environments.
>Broad Applicability – Suitable for chemical plants, food processing, pharmaceuticals, and coal-fired boilers where hygiene and corrosion resistance are critical.
Limitations
>Susceptibility to Chloride-Induced Stress Corrosion Cracking (SCC) – Prolonged exposure to chloride ions (e.g., coastal or chemical plant environments) can induce SCC in 304 SS due to its austenitic structure, compromising structural integrity.
>Temperature Limitations for Continuous Service – While resistant to intermittent temperatures up to 400°C, prolonged exposure above 500°C accelerates oxidation and reduces creep resistance, risking deformation in extreme thermal cycles.
>Cost-to-Performance Trade-Off in Harsh Environments – Economic Factor: Though cost-effective for mildly corrosive settings, 304 SS cages may exhibit shorter lifespans compared to higher-grade alloys (e.g., 310S) in highly abrasive or acidic conditions, increasing long-term maintenance costs.
