What is Pickling and Passivation?
Pickling and Passivation is a chemical process designed to remove contaminants and impurities from the surface of stainless steel products.

These contaminants left untreated, may compromise the protective oxide layer naturally formed on the surface of stainless steel, in turn leading to corrosion and degradation over time. Trans Vent’s process of tank emersion pickling offers the ideal process for treating fabrication surfaces for optimal corrosion resistance and uniformity, all conducted under strict health and safety standards. Through engaging Trans Vent for your pickling and passivation services, we can restore the integrity of the oxide protective layer, further extending your products lifespan.

How does Pickling and Passivation work?
During the passivation process, once the stainless steel surface is thoroughly clean of contaminants, your product is immersed in our acid tank, forming a passive oxide layer on the surface of the stainless steel. As this oxide layer develops, it acts as a barrier to protect the underlying stainless steel from corrosion.
