316L BA Mirror Steel Coil

316L BA Mirror Coil, suitable for medical devices

316L BA Mirror Stainless Steel Coil (00Cr17Ni14Mo2), compliant with GB/T 3280-2015, is an ultra-low carbon austenitic stainless steel.

  • Marine & Chemical Corrosion Resistance

    Pitting potential ≥+300 mV in 3.5% NaCl solution; superior crevice corrosion resistance compared with 304.

  • High Surface Finish

    BA treatment provides a smooth surface without secondary polishing, suitable for optical instruments and decorative components.

  • Ultra-Low Carbon Anti-Intergranular Corrosion

    C ≤0.03%, no risk of intergranular corrosion in welded heat-affected zones.

FAQ

What does BA mirror finish mean?

BA (Bright Annealed) mirror finish provides a smooth, reflective surface with excellent cleanliness.

What applications use 316L BA mirror steel coils?

Architectural decoration, food processing equipment, medical devices, and cleanroom environments.

Does the BA finish affect corrosion resistance?

No. The corrosion resistance of 316L remains unchanged, with improved surface cleanliness.

Can BA mirror coils be processed further?

Yes. Coils can be slit, polished, or cut to length.

Are protective films available for BA mirror coils?

Yes. PVC or laser protective films can be applied to prevent surface damage.
