When working with stainless steel, the metal surface can easily become stained, corroded or contaminated. Processes such as welding (and other fabrication techniques) may expose the metal to external elements that interfere with its overall chemical composition. Passivation, also called spray pickling, is a useful technique that can be used to restore a stainless steel surface. The process involves spraying a protective layer that removes oxides, iron ore contamination and oils from the surface of the metal. Read More
