Passivation - Passivating - Chemical Passivation


Why does stainless steel Rust? When the correct alloy has been chosen for a specific environment, and it still rusts, then something has likely affected the surface of the material. Real-world fabrication, welding and handling of stainless steel components will leave surface contaminates. These contaminates, including weld oxides and embedded particles, hinder stainless steel’s natural ability to resist corrosion. Pickling and/or Passivation can remove these surface contaminates, and allow the material to perform as it is engineered.
