WebSep 30, 2024 · At its core, passivation is a popular and effective way to finish metals like steel. In stainless steel, the passivation process removes free iron from the surface material using acid. The end result is steel covered with a passivation film, which is less likely to react with water and to resist erosion and rust to a higher degree.
