316L Stainless Steel Coil BA Bright Annealed Finish ASTM A240 0.5mm-2.0mm 1219mm Marine Grade Corrosion Resistant
316L Stainless Steel Coil - Bright Annealed BA Finish
Our 316L stainless steel coil features molybdenum alloying (2-3% Mo) that dramatically enhances corrosion resistance, particularly against chlorides, salt spray, and industrial solvents. The bright annealed (BA) finish delivers a mirror-like reflective surface through controlled atmosphere annealing, eliminating the need for post-process polishing. This premium marine-grade product is the top choice for chemical processing, offshore platforms, and coastal infrastructure in Middle East, Southeast Asia, and European markets.
Key Features
- Enhanced Chloride Resistance: Molybdenum content (2-3%) provides superior resistance to pitting and crevice corrosion in salt-laden environments
- Bright Annealed Finish: Achieved through hydrogen atmosphere annealing, producing a reflective surface without additional polishing
- Low Carbon Content: Max 0.03% carbon minimizes carbide precipitation during welding, ensuring intergranular corrosion resistance
- Excellent Weldability: Low carbon variant eliminates the need for post-weld annealing in most applications
- High Temperature Performance: Maintains mechanical properties and corrosion resistance at temperatures up to 450°C
