Product Description
Stainless Steel Round Tubes 316L are a versatile austenitic chromium-nickel alloy renowned for its excellent corrosion resistance, good formability, and ease of fabrication. Stainless Steel Round Tube 316L maintains robust mechanical properties across a wide temperature range, establishing itself as a fundamental material for fluid conveyance, structural components, and process equipment in demanding environments. These seamless tubes also exhibit outstanding resistance to oxidation and scaling at elevated temperatures.
Stainless Steel Round Tubes 316L are particularly valued for their combination of hygienic properties, strength, and ductility. A defining characteristic is their inherent ability to form a protective chromium oxide surface layer that self-repairs, enabling long service life in applications exposed to corrosive media, from mild chemicals and foodstuffs to atmospheric conditions. The seamless construction ensures superior pressure integrity and a smooth internal bore critical for efficient flow and cleanliness.
Resists pitting/crevice corrosion in chloride-bearing environments；
Self-regenerating chromium-based passive film ensures protection across diverse chemical media；

FAQ
316L flexible stainless steel round tube (also called SS corrugated tube, bellows tubing or flexible metal hose) is made of low-carbon 316L stainless steel strip, helically formed and welded. It offers excellent flexibility, high pressure resistance and superior corrosion resistance, widely used in vacuum lines, medical equipment, gas transfer and instrumentation.
316L contains molybdenum (Mo 2-3%) and lower carbon content, providing better resistance to pitting corrosion and chloride environments than 304. It is the preferred medical-grade and marine-grade flexible tubing material, especially in food, pharmaceutical and offshore applications.
Yes, our 316L flexible tubes are FDA-compliant, ISO 10993 biocompatible, electro-polished (EP) inner surface Ra≤0.25μm, widely used as endoscope shafts, catheter tubing, and sanitary beverage transfer hoses.
Free samples (≤30cm) are available. You only pay express cost. Contact us with required OD, wall thickness and application, we will arrange within 24 hours.
