Your stainless steel parts are prone to corrosion with regular machining. Maximize their resistance with Bales’ highly effective passivation services.
Our process uses citric acid to dissolve the free iron and foreign particles that cause rust and oxidation which creates a transparent oxide surface layer that’s highly resistant to mild corrosion.
Citric acid passivation is less hazardous than nitric acid passivation. It doesn’t require the use of mineral acids or sodium dichromate, which have safety and disposal issues.
Citric acid is an environmentally friendly substance. The Environmental Protection Agency and U.S. Food & Drug Administration classify citric acid with the “Generally Recognized as Safe” designation.
Citric acid passivation cycles are typically shorter than nitric acid’s. That means faster parts processing and lower costs.
When it comes to SS passivation, Bales’ citric acid solution is the winner. Maximize the corrosion resistance of your components while limiting the environmental impact. Looking for a reliable finishing resource that you can use every day? Get our Mold Finishing Guide!
