Product Description
Pipes/Tubes Stainless Steel SUS304 are a versatile austenitic chromium-nickel alloy renowned for its excellent corrosion resistance, good formability, and ease of fabrication. Pipes/Tubes Stainless Steel SUS304 maintain 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.
Pipes/Tubes Stainless Steel SUS304 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；
