Product Description
304 BA Stainless Steel Seamless Tube | Zero Carbon Precipitation
YUHAO 304 BA stainless steel seamless tube is manufactured using controlled-atmosphere bright annealing technology that eliminates carbon precipitation on the inner and outer surfaces. The result is a mirror-smooth, contamination-free bore ideal for ultra-high-purity (UHP) gas and fluid systems.
Key Features
- No Carbon Precipitation: Bright annealing in hydrogen/nitrogen atmosphere prevents surface carburization, ensuring no carbon particle release into process fluids.
- Intergranular Corrosion Resistance: Solution-annealed 304 stainless steel resists grain boundary attack, extending service life in corrosive environments.
- Seamless Construction: Cold-drawn seamless process eliminates weld seams, providing uniform wall thickness and superior pressure integrity.
- Bright Annealed (BA) Finish: Ra ≤ 0.4μm inner surface roughness minimizes particle entrapment and facilitates thorough cleaning.
- ASTM A269 Compliant: Manufactured and tested per ASTM A269 for general service seamless stainless steel tubing.
