The article informs on a primer on passivation presented by Jim Fritz, executive at the company TMR Stainless, presented at the National Tank Truck Carriers' 2011 Cargo Tank Maintenance Seminar held in Louisville, Kentucky. He stated that passivation means chemical treatment of stainless steel with acids that helps in forming a protective layer and its benefits include removal of free iron, and sulfides, and increased corrosion resistance. Also, he discussed the technique of pickling.
