ASTM A380 17Cleaning and Passivation of Stainless Steel

What is Passivation? How to Passivate Stainless Steel,and

Passivation of stainless steel can be performed using nitric acid or citric acid.However,there are many reasons that it is better to use citric acid.Many tests have shown that citric acid passivation is more effective than nitric because it only removes iron while leaving all of the chromium,nickel,and other good components intact.What is Passivation?
