Brief: Watch as we walk through the full process, from initial setup to real-world testing, of precision CNC milling for Hastelloy C-22 medical device parts. This demonstration showcases how we machine this hard, corrosion-resistant superalloy into complex geometries like thin-walled enclosures and intricate channels, ensuring dimensional accuracy and surface integrity for critical medical applications.
Related Product Features:
  • Precision CNC milling of Hastelloy C-22, a premier nickel-chromium-molybdenum-tungsten alloy with universal corrosion resistance.
  • Specialized machining for complex geometries including thin walls, deep cavities, and precision bores with tolerances as tight as ±0.025 mm.
  • Optimized processes to handle the material's work-hardening nature, using rigid machine tools and high-pressure coolant.
  • Post-processing includes electropolishing or passivation to restore the alloy's maximum corrosion resistance and achieve smooth surface finishes.
  • Manufactured under a Quality Management System compliant with ISO 13485 for medical device applications.
  • Full material traceability with Mill Test Certificates and 100% critical dimension verification using CMM.
  • Ideal for long-term implantable devices, surgical instruments, and diagnostic equipment exposed to aggressive environments.
  • Cleanroom packaging and cleaning per medical device protocols to ensure component purity and reliability.
Faqs:
  • What makes Hastelloy C-22 suitable for medical device parts?
    Hastelloy C-22 offers exceptional resistance to a wide spectrum of corrosive chemicals, including chlorides and acids, along with excellent biocompatibility and thermal stability, making it ideal for long-term implantable devices and surgical tools in aggressive environments.
  • What tolerances can be achieved with your precision milling process?
    Our standard dimensional tolerance is ±0.025 mm on critical features, with high-precision tolerances of ±0.0125 mm achievable for select features. True positional tolerance can be held within 0.05 mm or better.
  • How do you ensure the corrosion resistance of the machined parts?
    After machining, we perform critical post-processes like electropolishing or chemical passivation per ASTM A967 to remove surface contaminants and restore the optimal passive oxide layer, ensuring maximum corrosion resistance for the final component.
