In industries with extremely high demands for safety and stability, such as food processing,chemical manufacturing,and pharmaceutical production,screen, filtration, and classification equipment not only impacts production efficiency but also directly affects product quality and compliance risks.Stainless steel mesh, as a core filtration component, has become a key focus for companies in equipment selection and quality management,considering its material selection, manufacturing process, and applicable standards.

        Ⅰ. Common requirements for stainless steel mesh in different industries

        Material Safety and Stability:  The sieve mesh, in direct contact with materials during prolonged use, must possess excellent chemical stability to prevent the release of harmful substances or reactions with the processed medium.

        Cleanability and Hygiene: The sieve mesh surface should be smooth and free of crevices, facilitating cleaning and disinfection to prevent residue buildup, bacterial growth, or cross-contamination.

        Structural Strength and Service Life: Under high-frequency vibration, pressure changes, or continuous production conditions, the sieve mesh needs to maintain stable mesh size and overall strength to prevent deformation or wire breakage.

        Ⅱ. Food industry: Focusing on "food contact safety" as the core principle.

        In the food processing industry, stainless steel mesh is primarily used for raw material screening, powder classification, and liquid filtration.  The core standard revolves around "food-grade safety."

        • Common materials: 304 and 316 stainless steel filter disc

        304 stainless steel is widely used in general food processing due to its good corrosion resistance and cost-effectiveness;for high-salt high-acid,or high-temperature environments, 316 stainless steel, due to its molybdenum content, offers superior performance.

        • Surface treatment requirements:

        The mesh surface must be polished or electrolytically treated to reduce surface roughness,minimize material adhesion,and meet food hygiene management standards.

        Ⅲ. Chemical industry: Emphasis on corrosion resistance and compatibility.

        The chemical industry has more complex requirements for stainless steel mesh screens, as the screens often need to withstand acidic, alkaline, organic solvent, or high-temperature and high-pressure environments.

        • Emphasis is placed on corrosion resistance.

        The corrosion mechanisms of different chemical media on metal materials vary, so it is necessary to select the appropriate stainless steel grade based on actual working conditions, and use higher-grade alloy materials when necessary.

        • Mesh Accuracy and Stability

        In chemical powder classification or catalyst screening, mesh consistency directly affects product particle size distribution, requiring higher precision in screen weaving.

        • Structural Strength Design

        Chemical filter screens or pressure filtration equipment typically handle high loads, so the screen mesh needs to have good fatigue resistance to reduce downtime losses caused by frequent replacements.

        Ⅳ. Pharmaceutical industry: The scenario with the most stringent standards.

        In the pharmaceutical manufacturing field, stainless steel mesh is not only a production component but also an integral part of the quality system, and its usage standards are typically higher than those in the food and chemical industries.

        • High-Purity Material Requirements:The pharmaceutical industry often uses 316L stainless steel to reduce impurity content and the risk of leaching, meeting the demands of high-cleanliness production.

        • Verifiability and Traceability:The mesh material, batch, and manufacturing process must be traceable, facilitating audits by quality systems such as GMP.

        • Easy Cleaning and Disinfection Design:The mesh must be compatible with cleaning and sterilization processes such as CIP and SIP, maintaining stable performance even after repeated high-temperature or chemical cleaning.
