Passivation
MAXIMIZE THE LIFESPAN OF YOUR STAINLESS STEEL PARTS
Your stainless steel parts are prone to corrosion with regular machining. Maximize their resistance with Bales’ highly effective passivation services.
Our SS passivation 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.
WHY CITRIC ACID?
Safety
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.
Low Environmental Impact
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.
Greater Efficiency
Citric acid passivation cycles are typically shorter than nitric acid’s. That means faster parts processing and lower costs.
