AISI 316L BA Bright Annealed Cold Rolled Stainless Steel Coil
Our AISI 316L BA Bright Annealed Cold Rolled Stainless Steel Coil is engineered for the most demanding medical, pharmaceutical, and clean-tech applications. The Bright Annealed (BA) surface is achieved through controlled-atmosphere heat treatment that produces an ultra-clean, reflective, and oxide-free surface ideal for hygienic environments.
Key Features
- 316L Medical Grade: Low carbon with 2-3% molybdenum for superior pitting and crevice corrosion resistance, essential for sterilization and aggressive cleaning protocols.
- Bright Annealed Surface: Heat-treated in hydrogen/nitrogen atmosphere for a bright, clean, oxide-free finish without pickling. Ra typically ≤ 0.05 μm for superior cleanliness.
- Full Traceability: Each coil carries heat number markings and is accompanied by full EN 10204 3.1 MTC documenting chemical composition and mechanical properties.
- Tight Gauge Control: Precision cold rolling delivers gauge tolerances within ±0.01mm for consistent performance in automated medical device manufacturing.
Applications
Ideal for surgical instrument components, pharmaceutical processing equipment, implant-grade base material, clean room panels, laboratory bench tops, and medical device enclosures where surface cleanliness and corrosion resistance are paramount.
