anodic cleaned Ra ≤ 0,40 µm
bright finish Ra ≤ 0,40 µm

Safetron with its premium surface qualities bright finish (Ra ≤ 0,40µm) and electropolished (Ra ≤ 0,25µm) is primariliy used in the pharmaceutical and biotechnological industries for WFI, serums and parenteral drugs. This surface finish guarantees shorter cleaning and sterilisation times. If corrosive media shall be used, safetron can also be delivered in the qualitiy UNS N08904 (904L)/1.4539.
