Safe & Environmentally-Friendly 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. Citric acid concentrates solely on pulling the free irons out of the passivated part, making it more corrosive resistant.
Using the citric acid passivation method can improve a part’s resistance to corrosion considerably. Though stainless steel can never be 100% corrosion-proof, our citric passivation process gets it as close as possible.
