Pickling, passivation, electropolishing steel.
Chemical treatment for removing impurities, contamination, stains and material produced by welding. The finish is achieved with this process is a homogeneous surface, clean and passivated with corrosion protection and matte or glossy appearance.
The electropolishing is a surface treatment which is performed through an electrolytic process by anodic dissolution of the metal surface to be treated, producing a levelling of the material basis leading to a bright finish and improve the properties of stainless steel Austenitic (non-ferrous).
The most common types are AISI 304, 316.
