Citric Acid Passivation

For world-class citric acid passivation services, look no further than RP Abrasives. We use a citric acid based solution to passivate stainless steel & titanium because it’s the most effective and environmentally friendly option available. Citric acid concentrates solely on pulling the free irons out of the part being passivated allowing it to be more corrosive resistant.

Using the citric acid passivation method, can improve a parts resistance to corrosion considerably. Though stainless steel can never be 100% corrosion-proof, our citric passivation process gets it as close to that as possible.

  • Passivating from small batch sizes to large parts
  • Passivate using deionized water and citric acid
  • Testing of passivated parts with a copper sulfate test
