Product Description
304 Stainless Steel Seamless Tubes are a versatile austenitic chromium-nickel alloy renowned for its excellent corrosion resistance, good formability, and ease of fabrication. 304 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.
304 Stainless Steel Seamless Tubes 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；
Seamless cold-rolling delivers homogeneous circumferential strength；
Meets full lifecycle reliability requirements for high-pressure fluid systems；
Forms stable chromia barrier layer under elevated temperatures；
Effectively resists oxidation-induced spallation；
Austenitic structure maintains superior impact toughness at cryogenic temperatures；
Eliminates risks of low-temperature brittle fracture；
Certified per international biocompatibility standards；
Resists degradation from medical sterilization processes；
Strain-hardening characteristics optimize cold-forming processing window；
Simultaneously enhances strength and ductility；
