Our company also does passivation process on request.
This process consists in removing a part of the iron layer from the surface of the metal part and so it creates a thin protective oxide barrier. By doing so, this leads to a long-life span of protection against corrosion. This method is mandatory for all metals that come into contact with the human body.
The medical passivation process is in particular described in the specifications standards ASTM A967.
Our teams have the necessary competence to apply this method to all types of medical austenitic and martensitic stainless-steel.
