Food and pharmaceutical industry
Stainless steel employed in the food and pharmaceutical industries adheres to core requirements of ‘hygienic safety + corrosion resistance and ease of cleaning + non-toxic compliance’. It must meet stringent standards such as GMP and FDA to prevent material contamination and microbial proliferation, serving as a critical material for safeguarding product purity and safety.The predominant materials are concentrated within the 300 series of austenitic stainless steels, with core grades suited to specific applications: - 304 stainless steel contains 18% chromium and 8% nickel, offering strong chemical stability, being non-toxic and odourless, with excellent workability (suitable for stamping, welding, and mirror polishing) and cost-effectiveness. It is widely used in food processing equipment (such as mixers, storage tanks, and conveying pipelines), and pharmaceutical packaging components. It withstands routine acid-alkali exposure and high-temperature cleaning. 316L stainless steel incorporates molybdenum into the 304 composition, significantly enhancing resistance to pitting and crevice corrosion. It handles high-salt, high-acid foods (e.g., pickled goods, fruit juices) and pharmaceutical disinfectants (hydrogen peroxide, alcohol) or pharmaceutical solutions. Common applications include pharmaceutical reactors, sterile piping systems, and core components of food sterilisation equipment. 316Ti stainless steel gains enhanced stability from titanium, making it suitable for high-temperature sterilisation equipment (e.g., 121°C steam sterilisation), such as pharmaceutical freeze dryers and inner liners of food sterilisation autoclaves.The core characteristics of these stainless steels are hygienic processing: internal surfaces require mirror polishing (Ra ≤ 0.4μm), with no weld seams, dead corners, or depressions to prevent microbial growth; The material exhibits no heavy metal leaching, complying with food contact metal safety standards. Its broad temperature tolerance (-20°C to 400°C) accommodates diverse processes including frozen storage and high-temperature sterilisation. It facilitates easy cleaning and disinfection, withstanding repeated acid/alkaline washing and steam sterilisation without compromising material properties.Application scenarios span the entire industrial chain: - Dairy processing equipment, beverage production lines, and condiment storage tanks in the food industry; - Pharmaceutical reactors, centrifuges, medicinal packaging materials (e.g., stainless steel syringe push rods), and sterile operating theatre instruments in the medical sector; - Raw material mixing equipment and finished product storage tanks in the health supplement industry. Its compliance and stability ensure the safety and purity of food and pharmaceutical products while extending production equipment lifespan and reducing cleaning and maintenance costs.
