Adinox Overseas is a world-renowned supplier and exporter of top-quality Stainless Steel 316 Tubes that has been designed to meet the challenging requirements of those industries where excellent resistance to corrosion and mechanical strength are a must. SS 316, under the UNS number S31600, is one of the most popular austenitic stainless steel grades after grade 304.
Our Stainless Steel 316 Tubes are produced in accordance with international requirements like ASTM A213 for seamless tubes and ASTM A269 for welded tubes. These specifications guarantee that tubes adhere to accurate dimensional tolerances, pressure levels, and quality thresholds that are demanded by engineers and project planners across the globe. 316 tubing is supplied by us in a number of formats like seamless, welded, bright annealed, U-bend, and instrument tubing to suit a broad spectrum of applications.
Molybdenum content in SS 316 Tubes provides superior acid and saltwater corrosion resistance over SS 304. The tubes find wide applications in petrochemical, pharmaceutical, food processing, pulp and paper, offshore platforms, and marine systems. The tubes are particularly valuable in environments subject to chlorides and other halides, where they offer superior performance and reliability over a sustained period. SS 316 also provides excellent resistance to intergranular corrosion and endures at 870°C in intermittent service and 925°C in continuous service.
Adinox Overseas makes sure that all Stainless Steel 316 seamless tubes go through intense non-destructive testing, pressure tests, dimensional verification, and visual examinations. We issue third-party inspection reports, mill test certificates (EN 10204 3.1/3.2), and material traceability in order to maintain our guarantee of transparency and quality. The tubes are characterized by excellent dimensional tolerance, a clean internal finish,and excellent mechanical strength and are suitable for applications in heat exchangers, instrumentation systems, and pressure tubing.
