Understanding Pickling and Passivating in Metal Fabrication

When it comes to metal fabrication, many processes are used to prepare and finish the material. Two of the most important processes are pickling and passivating. These are often used interchangeably, but they are actually two distinct processes that serve different purposes. In this blog post, we’ll take a closer look at pickling and passivating and explain what they are, why they’re important, and how Steelmor can help.

Unpacking Pickling

Pickling is the process of removing surface impurities from metal using an acid solution. The acid solution is typically a mixture of hydrochloric and nitric acid, which creates a reaction that dissolves any surface contaminants, such as rust, scale, and other oxides. This process leaves the metal with a clean, smooth surface ready for further processing or finishing.

Understanding Passivating

Passivating, on the other hand, is the process of creating a passive layer on the surface of the metal that resists corrosion. This is typically done by immersing the metal in an oxidizing solution, such as nitric acid or sodium dichromate. This process creates a thin layer of oxide on the surface of the metal that prevents further oxidation and corrosion.

Both pickling and passivating are critical processes in metal fabrication. Pickling removes impurities and prepares the metal for further processing or finishing, while passivating protects the metal from corrosion and ensures its longevity. These processes are especially important for stainless steel and other high-performance alloys, which are used in a variety of industries, including aerospace, medical, and chemical.
