About Passivation:


What is passivation?

Passivation is the super cleaning of stainless steel to remove any free iron contamination left on the surface from the machining / fabrication processes which could result in premature corrosion.


Why passivate?

The passivation process results in the formation of a very thin, transparent oxide film which protects the stainless steel from corrosion.


What passivation processes does Classic Metal provide?

We offer nitric acid passivation to a variety of governmental, industrial and commercial specifications including but not limited to AMS 2700, QQ-P-35, ASTM A-967 and ASTM A-380.
