Super-Clean, Precision Stainless Steel Tubes for Instrumentation, Pharma, Food, High-Purity & Clean Processing Lines
Inox Steel India
Inox Steel India is a leading manufacturer, stockist, and exporter of Bright Annealed Stainless Steel Tubes produced according to ASTM A269 with BA (Bright Annealed) finish.
These tubes are processed using a controlled atmosphere bright annealing furnace, delivering a mirror-smooth, scale-free, contamination-free internal & external surface.
BA (Bright Annealed) tubes are essential for industries requiring:
ASTM A269 BA tubes are used in pharma, biotech, instrumentation, semiconductor, food processing, dairy, chemical injection lines, and automotive precision systems.
Bright Annealing is a heat treatment process performed inside a high-purity hydrogen atmosphere furnace, ensuring:
All tubes are manufactured with strict ID cleanliness and OD tolerance suitable for global instrumentation standards.
1. Cold Drawing / Rolling
Ensures precise dimensions and mechanical properties.
2. Bright Annealing in Controlled Atmosphere
Hydrogen environment → bright, oxidation-free finish.
3. Pickling + Passivation
Removes any impurities, ensuring sterile internal surfaces.
4. Polishing (Optional)
ID/OD polishing for high-purity & semiconductor-grade applications.
5. NDT Testing
Ensures tubes are defect-free and suitable for high-purity flows.
