Passivation is a process used to enhance the corrosion resistance of stainless steel.<\/p>\n

Passivation is a chemical treatment applied to stainless steel to remove free iron from the surface. This process creates a thin, protective oxide layer that prevents the steel from reacting with air and causing corrosion.<\/p>\n

The process typically involves immersing the stainless steel in an acid solution, such as nitric or citric acid.<\/p>\n

This treatment removes contaminants, allowing the formation of a passive oxide layer that shields the steel from further oxidation.<\/p>\n

The primary benefit is improved resistance to rust and corrosion. Passivated stainless steel components have a longer service life.<\/p>\n

The process also removes surface contaminants, making the steel cleaner and more suitable for sanitary applications.<\/p>\n

Passivation is widely used in industries where corrosion resistance is crucial, such as food processing, pharmaceuticals, medical devices and aerospace.<\/p>\n","protected":false},"excerpt":{"rendered":"
