Our ASTM A312 TP304 (UNS S30400) Stainless Steel Seamless Tube is a premium austenitic stainless steel product designed for industries where hygiene, corrosion resistance, and product purity are non-negotiable. Manufactured through advanced seamless cold-drawing processes, this tube delivers exceptional surface finish, cleanliness, and mechanical properties that meet the strictest standards of the food, pharmaceutical, chemical, and biotechnology industries. With full BV, SGS, and ABS certifications, our TP304 tubes provide reliable, contamination-free fluid handling for critical processing applications.
Key Features & Advantages
Premium 18/8 Austenitic Stainless Steel: Composition of 18% Chromium and 8% Nickel provides outstanding general corrosion resistance against organic acids, cleaning chemicals, and atmospheric exposure, with excellent performance across a wide range of pH environments.
Superior Surface Finish: BA (Bright Annealed) surface finish with Ra ≤0.8μm for the internal surface ensures minimal particle adhesion, easy CIP (Clean-in-Place) and SIP (Steam-in-Place) compatibility, and resistance to biofilm formation.
Exceptional Mechanical Properties: Tensile strength ≥515 MPa, yield strength ≥205 MPa, and elongation ≥35% provide excellent formability for bending, expanding, and fabrication without compromising structural integrity.
Complete Sterilization Compatibility: Suitable for steam sterilization at temperatures up to 121°C, chemical sterilization with hydrogen peroxide and peracetic acid, and hot water sanitization cycles.
Orbital Welding Ready: Consistent wall thickness and roundness enable high-quality automatic orbital welding for hygienic tube joining in process piping systems.
Application Scenarios
Food and beverage processing: dairy, brewery, winery, and soft drink production lines
Pharmaceutical manufacturing: WFI (Water for Injection) systems, pure steam lines, and API processing
Biotechnology: fermentation, cell culture, and downstream purification systems
