Strategic Material Selection for CNC Machined SUS316L Stainless Steel Components

Selecting SUS316L stainless steel for high-performance CNC machining involves assessing corrosion resistance, biocompatibility, and mechanical properties:

  • Medical implants, surgical instruments, and pharmaceutical equipment components significantly benefit from SUS316L stainless steel, providing superior biocompatibility (ASTM F138 standard) and corrosion resistance, particularly in chloride-rich or corrosive environments.

  • Marine fittings and components exposed to harsh, salty conditions are ideally suited to SUS316L, reducing the risk of corrosion-related failures.

  • Where enhanced corrosion resistance is essential without strict biocompatibility needs, SUS316 stainless steel is a suitable alternative.

  • General industrial fittings and less demanding medical instruments often select SUS304 stainless steel to balance corrosion resistance and machinability.
