316L Stainless Steel Coil With BA Finish For Medical Equipment

316L Stainless Steel Coil with BA Finish for Medical Equipment undergoes a professional bright annealing process, resulting in a uniform mirror-like finish with a roughness Ra≤0.4μm. It is free of oxidation, scratches, and burrs, allowing for direct application in precision machining without subsequent polishing. This significantly reduces production costs for medical equipment and avoids the risk of contamination from impurities generated during polishing.

Medical Device Housings: For housings of surgical instruments, testing equipment, and sterile operating tables, the BA finish provides a beautiful and clean appearance, is easy to clean and sterilize, and possesses excellent corrosion resistance. It is resistant to yellowing and rusting over long-term use, enhancing the quality and lifespan of medical equipment.

Medical Catheter Substrate: As the core substrate for infusion catheters, interventional catheters, and drainage catheters, it features uniform thickness, good ductility, and strong corrosion resistance. It can withstand human body fluids and disinfection media, with no impurities precipitating, ensuring safe catheter use and suitability for medical implantation scenarios.

Sterile Equipment Accessories: Such as sterile storage tanks, disinfection equipment, infusion set accessories, and blood flow guiding stent delivery systems, it has no weld seams or oxide layers, meeting sterile environment requirements, avoiding media contamination, and ensuring the sterility and stability of medical equipment.

Bright Annealing Process Details: A continuous bright annealing furnace is used, controlling the annealing temperature at 1080~1150℃. The holding time is adjusted according to the thickness (1~2 minutes per 1mm wall thickness). A high-purity hydrogen-nitrogen mixture (dew point ≤ -60℃) is introduced as a protective atmosphere. Slight positive pressure is maintained inside the furnace to prevent air infiltration and oxidation, ensuring a bright, flawless surface while eliminating work hardening and restoring material plasticity.

Seamless Finish: Utilizing cold rolling and seamless processing, the entire process is weld-free, avoiding potential corrosion and cracking issues at weld seams. Precision grinding and polishing further ensure a smooth, flat surface without any weld marks, making it suitable for medical sterile environments and precision machining requirements.

Precision Control: Employing multi-stage vacuum annealing furnaces and precision testing equipment, temperature sensor errors are ≤±5℃, thickness and width tolerances are strictly controlled within ±0.02mm, straightness is ≤0.5mm/m, and surface roughness Ra≤0.4μm. Each roll undergoes triple testing for dimensions, surface finish, and corrosion resistance, preventing substandard products from leaving the factory.
