Pickling and Passivating Stainless Steel

This resource describes the surface treatments known as pickling and passivation that can be applied to stainless steel. Pickling uses nitric and hydrofluoric acids to remove a thin layer of metal from the surface.  Passivation uses nitric acid to improve the quality and thickness of the passive layer on the surface. Procedures for removing weld heat tint and rust contamination are explained.

Energy conservation in stainless steel cold rolling applications

After exhaustive tests, a high-quality rolling oil was formulated using a combination of ester and paraffinic mineral oil. It is observed that this new oil can save 14% of energy consumed by a laboratory mill compared with conventional rolling oils. In production mills, nearly the same energy conservation level can be achieved.

Pickling and Passivation

Stainless steel can corrode in service if there is contamination of the surface. Both pickling and passivation are chemical treatments applied to the surface of stainless steel to remove contaminants and assist the formation of a continuous chromium-oxide, passive film. Pickling and passivation are both acid treatments and neither will remove grease or oil. If the fabrication is dirty, it may be neccesary to use a detergent or alkaline clean before pickling or passivation.
