The Pickling process utilizes more aggressive acids than those used in passivation. The acids used when pickling the stainless steel surface can remove or dissolve existing oxidation, weld oxides, embedded particles and scale that can build up on stainless steel during real-world fabrication, welding and handling. Pickling is used extensively to clean and prepare stainless steel fabrications for service within demanding environments. Without pickling, stainless steel fabrications will not resist corrosion as they are engineered to do.
