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.
